 Abstract    tr u c tu r e o f th e S o lv a te d S tr o n tiu m a n d B a riu m I o n s in A q u e o u s, D im e th y l S u lfo x id e a n d P y r id in e S o lu tio n , a n d C r y s ta l S tr u c tu r e o f S tr o n tiu m a n d B a r iu m H y d r o x id e O c t a h y d r a te Dedicated to Prof. Hitoshi Ohtaki on the occasion of his 60th birthday Single crystal X-ray data, collected at 298 K, are used to redetermine the crystal structure of the non-isomorphic compounds [Sr(H20)8](0H)2 and [Ba(H20)8](0H)2. The eight water oxygen atoms form distorted Archimedean antiprisms around the octahydrated metal ions with mean metal ion-oxygen distances 2.62 and 2.79 Ä for strontium and barium, respectively. A second coordination shell of 24 hydrogen-bonded oxygen atoms with mean metal ion-oxygen distances M • • • O" 4.76 and 4.80 A, respectively, is observed. The hydroxide ions in both structures have an unusual hydrogen bond arrangement with 5 bonds accepted and one donated. The structure of the solvated strontium and barium ions in aqueous, dimethyl sulfoxide and pyridine solutions has been studied by means of large angle X-ray scattering and extended X-ray absorption fine structure spectroscopy techniques. In aqueous solution independent determinations of the first-sphere metal-oxygen coordination by the two techniques resulted in the bond lengths Sr-O 2.63 (2) and Ba-O 2.81 (3) A, and for both metal ions a hydration number of 8.1 (3). The second coordination spheres are very diffuse with only about 13 water molecules at similar M • • • O" distances as in the crystal structures and 2-3 water molecules closer to the metal ions. In dimethyl sulfoxide solution both ions were found to coordinate 6.0 (5) solvent molecules with the distances Sr-O 2.54(1), Sr -S 3.77(1) A, and Ba-O 2.76(1), Ba -S 3.99(1) A. For the solvated ions in pyridine solution EXAFS measurements yielded the distances Sr-N 2.57 (2) and Ba-N 2.78 (3) A, with a probable solvation number of 6. Correlations of hydration enthalpies and partial molar volumes with experimental M-O bond distances in aqueous solution are used to discuss hydration numbers and bond character for all of the alkaline earth metal ions.

 Title    Kristallstrukturuntersuchung an einem Strontium-Vanadyl-Vanadat: Sr2(V 0 )V 20 8 Crystal Structure Investigation of the Strontium Vanadyl-Vanadate: Sr2( V 0 ) V 20 8  
 Abstract    Single crystals of Sr2(V 0)V 20 8 have been prepared by quenching melts from higher tem­ peratures. This compound represents a new structure type and crystallizes with monoclinic symmetry, space group C |h-I 2 la, a = 6.929, b = 16.246, c = 7.260 A, ß = 115.82°, Z = 4. The point positions occupied by V5+ show tetrahedral coordination. The refinement of the V4+ position led to split positions with acentric orientations of V4+ in the octahedral O2-surrounding. It results in a square pyramidal coordination with one short V -O distance typically for vanadyl groups.

 Abstract    Single crystals of the hitherto unknown compound SrM nT e06 have been prepared from Sr(0H)2-8H20 , M n C 0 3(aq) and T e 0 2 in air by crystallization below the melt range. X-ray in­ vestigations showed hexagonal symmetry, space group D3h-P62m, lattice constants a = 5.143(1), c = 5.384(2) A, Z = 1. SrM nTe06 is characterized by staggered [(Mn/Te)60 18] Kagome layers along [001]. These layers are connected by Sr2+ ions, resulting in S r0 6 prisms isolated from each other. The structure is discussed with respect to the connection of Kagome nets in the quaternary oxides of the Ba3Ln40 9 type.

 Abstract    The new compound Sr2Cu304Cl2 was prepared in melts of SrCl2. A single crystal X-ray examination (a = 546.2, c= 1259.1 pm, space group D^-14/mmm) shows that the octahedral distortion of the [Cu304Cl2] 4 ~-network cannot be explained only by the JAHN-TELLER effect.

 Title    Zur Kristallstruktur von Sr6(Cr04)3Cl On the Crystal Structure of Sr5(Cr04)3Cl  
 Abstract    Single crystal X-ray investigation shows that Sr5(Cr04)3Cl is not isotypic with the apatite structure as being affirmed up to now. Chlorine occupies a position other than z = 0.250 implying the lower symmetry Cg-P63. As a consequence one strontium coordination sphere changes from octahedral to trigonal prismatic.

 Abstract    Calcium-and strontium bis[bis(trimethylsilyl)amide] react with bis(trimethylsilyl)arsane in tetrahydrofuran to give the corresponding tetrakis(tetrahydrofuran-O) metal bis[bis(trime-thylsilyl)arsanides]. The calcium derivative crystallizes in the triclinic space group P I with a = 1191.7(2), b = 1232.0(2), c = 1655.0(2) pm, a = 102.46(1)°, ß = 107.92(1)°, y = 104.66(1)° and Z = 2, the strontium derivative in the orthorhombic space group Pbca with a = 2153.4(3), b = 1852.2(3), c -2182.4(3) pm and Z = 8. Both m olecules exist as frans-isomers with a nearly linear A s -M -A s moiety; however, the strontium analogue contains two remarkably different configurations for the arsenic atoms. One A s atom is surrounded nearly trigonally planar with a S r -A s bond length of 310 pm, whereas the other pnictogen atom has an angle sum of 338° with a S r -A s distance of 315 pm.

 Abstract    Dark green single crystals of Sr2(VO)P2Ox have been prepared by solid state reactions in closed quartz tubes. X-ray investigations led to monoclinic symmetry, space group C2h-I2/c/, a = 6.744(4), b = 15.866(4), c = 7.032(2) Ä, ß = 115.41(2), Z = 4. Sr2(VO)P2O s is isotypic to Sr2(VO)V2Os and shows V4+ in split positions. The split positions are in non-centric octahedral coordination forming a short vanadium to oxygen distance typical for the vanadyl group. The crystal chemistry of the monovanadyl orthophate Sr2(VO)P2O x is discussed considering related divanadyl phosphates.

(I) is isotypic to Sr2(V 0)V 20 8 and Sr2(V 0)(P 0 4)2. (II) shows significant differences to the strontium compounds as well as to Ba2(V 0)(V 0 4)2. The differences of the crystal chemistry and the similarity of (II) to Ba2(V 0)(P 0 4)2 H20 are discussed.

 Title    AgSrfByO^]: Das erste wasserfreie quaternäre Silber(I)-Borat mit vierfach koordiniertem Silberion und einem neuartigen Boratanion AgSr[B70 12]: The First Anhydrous Quaternary Silver(I)-Borate with Fourfold Coordinated Silver Ion and a New  
 Abstract    Single crystals of AgSr[B70 , 2] were obtained by using a B20 3 flux-technique and Ag2C 0 3 and SrC 03 as starting materials in a silver ampoule at 800 °C. X-ray investigations on single crystals led to the space group C 2/c with a = 664.2(5); b = 1153.6(3); c = 2198.0(6) pm; ß = 92,52(3)°; Z = 8. Ag+ is fourfold coordinated by oxygen atoms and forms distorted A g04 tetrahedra while Sr2+ has nine nearest neighbours. The compound contains a hitherto unknown two dimensional borate anion [B70 i 2]3-which contains four trigonal planar B 0 3 groups and three B 0 4 tetrahedra per unit.

 Abstract    (V0)(P04)2 und BaC d(V 0)(P04)2: Zum BaZn(V0)(P04)2-Typ verwandte, jedoch nicht isotype Vanadylphosphate SrZ n(V 0)(P 04)2 and B a C d (V 0)(P 04)2: Vanadylphosphates Related but not Isotypic to the B aZ n (V 0)(P 04)2 Type Single crystals of the compounds S rZ n (V 0)(P 0 4)2 (I) and B aC d(V 0)(P04)2 (II) ha­ ve been prepared by solid state reactions in evacuated quartz tubes. X-ray investigati­ ons confirmed orthorhombic symmetry, space group D ^-P bca, lattice constants a/b/c (I): 9.066(1)/9 .0 1 2 (l)/l7.513(1) A and (II); 8.838(4)/8.915(4)/19.374(9) Ä, Z = 8. Initially assu­ med isotypies of (I) and (II) to B aZ n(V 0)(P 04)2 proved to be erroneous considering significant details of the connectivity of the Z n 0 4 and P 0 4 tetrahedra (I) and the coordination sphere of cadmium (II), respectively. The similarities and differences of the crystal chemistry relation to (I) and (II) are discussed with respect to B a Z n(V 0)(P 04)2. The Coulomb terms of the lattice energies of vanadyl M2(V 0)(P 0 4)2 and divanadyl M (V 0)2(P 0 4)2 phosphates are shown.
