 Title    Vier verschiedene Koordinationspolyeder um Cu2+ im Oxid-Arsenat-Phosphat Cu0  
 Abstract    (Cu,M g)3(As1_xPJt:0 4)2 (x = 0,3) Four Different Coordination Polyhedra Around Copper in the Oxide-Arsenate-Phosphate C u0(C u,M g)3(A s,_xP,.04)2 (x = 0.3) Single crystals of CuO(Cu,Mg)3[(As0.7P0.3)O4]2 have been prepared by crystallization from melts. The compound crystallizes with triclinic symmetry, space group C '-P l, a = 6.372(4), b = 7.643(7), c = 8.175(5) A, a = 98.59(6), ß = 112.26(3), 7 = 99.03(3)°, Z = 2. CuO(Cu,Mg)3[(Aso)7Po 3)0 4]2 is isotypic to Cu4(P 0 4)20 . X-ray investigations show square planar C u 04 polygons, twisted tetragonal C u 0 5 pyramids, C u 05 bipyramids and elongated (Cu,M g)06 octahedra.

 Title    Two Examples of Partial and Total Defects in the B a«Ln2Mo4O i6-Type: BaCu0 41 ■o,59Pr2Mo4 0 16 and BaBYb2Mo4Ojg  
 Abstract    Single crystals of (I) BaCu0.4iPr2M o4O 16 and (II) BaYb2M o40 16 have been prepared by flux technique. Both compounds crystallize with m onoclinic symmetry, space group C2h-C 2 /c with (I): a = 5.352(11), b = 12.888(2), c = 19.399(4) A; ß = 90.89(3)°; (II): a = 5.181(7), b = 12.467(3), c -19.350(3) Ä , ß -91.93(2)°, Z = 4. The crystal structure is characterized by i [ B a M 0 12]-chains along [010]. In the first case the M positions are occupied by copper by about 41%, in the second case these positions remain com pletely unoccupied. With respect to the crystal chemistry of the reference compound Ba(Cu0.22Mg() 78)Nd2Mo4O 16 all substan­ ces of the composition BaLn2M o40 16 should be written as Ba»Ln2Mo40 16 indicating the holes in th e^ B a M O i^ -c h a in s by ■.

 Title    Ein Oxometallat mit eindimensional flächenverknüpften Oktaederketten Synthesis and Crystal Structure of (C u,Fe)363M o3O i2. An Oxom etallate Showing One-Dimensional Chains of Face Sharing Octahedra  
 Abstract    Single crystals of (C u ,F e)3-63M o30 12 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group D : 2-P 2 12121, a = 5.0952(8), b = 10.637(2), c = 17.881(3) A , Z = 4. (C u ,F e)363M o3O i2 is isotypic to Cu385M o30 12 or (C u,Z n)3 75M o30 12. M olybdenum shows tetrahedral coordination by oxygen. Cu+ and Fe2+ are probably distributed statistically over four different point positions. Interesting features of the crystal structure are one-dim ensional chains of face shared (C u ,F e)0 6 octahedra.

 Abstract    Single crystals of (C u,M n)U M o30 12 have been prepared in sealed copper tubes. X-ray investiga­ tions lead to hexagonal symmetry, space group C|h-P63/m, a = 9.7895 (13), c = 6.202(1) A , z = 2. (C u ,M n)U M o30 12 is isotypic to CdThM o30 12.

 Title     
 Abstract    Single crystals of BaCuTe03T e 0 4 have been prepared by crystallisation from melts. X-ray investigations lead to orthorhombic symmetry, space group C2v-Ama2, a = 5.4869(8), b = 15.412(1), c = 7.2066(4) A , Z = 4. This compound represents a new structure type, containing B aO 10, C u 0 5, T e 0 6 and T e 0 4 polyhedra. The lone pair (E) of TeIV completes the TeIV0 4 polyhedron to a trigonal T e 0 4E bipyramid. The Te to E distance is estimated by calculations o f the Coulomb terms of lattice energy to 1.43 A .

 Title    Zwei monokline Kupfer-Oxovanadate des Magnesiums mit geordneter Metallverteilung: /w-Mg2CuV20 8 und MgCu2V20 8. Ein Beitrag zur Dimorphie von Mg2CuV2Os Two Monoclinic Copper Oxovanadates of Magnesium Showing Ordered Metal Distribution: m-Mg9CuV-,08 and MgCu  
 Abstract    Single crystals of ra-Mg2CuV20 8 (I) and MgCu2V20 8 (II) have been prepared by solid state reactions. The orange (I) and dark red (II) crystals show monoclinic symmetry, space group C2h -P2,/c, (I): a = 6.167(3), b = 8.172(5), c = 6.400(8) Ä, ß = 116.22(3)°, Z = 2; (II): a = 6.453(1), b = 8.342(2), c = 11.517(2) Ä, ß = 90.44(2), Z = 4. Both compounds show ordered metal distributions and vanadium in tetrahedral coordination by oxygen. (I) is characterized by elongated C u06 octahedra and (II) by trigonal C u 0 5 bipyramids. ra-Mg2CuV20 8 is the low temperature form of the formerly investigated orthorhombic o-Mg2CuV2Ö8. Calculations of the Coulomb parts of the lattice energy of the two crystal forms are discussed.

 Title    Über ein Blei-Kupfer-Tellurat PbC^TeOy mit Cu2+ in deformiert tetragonal pyramidaler und tetraedrischer Sauerstoffkoordination  
 Abstract    On a Lead C opper Tellurate P b C u 3T e 0 7 Containing C u2+ in D istorted Square Pyram idal and Tetrahedral O xygen C oordination B. W edel, Hk. M üller-B uschbaum * PbCu3T e07 has been prepared from the element oxides by solid state reaction in air. Single crystal X-ray work led too orthorhombic symmetry, space group D^-Pnma, a = 10.488(1), b = 6.353(2), c = 8.813(2) A, Z = 4. Cu(1)0 5 square pyramids and Te06 octahedra are members of the anionic part of the crystal structure, Cu(2) atoms show tetrahedral coordination by oxygen. The C u (2)2+ and the Pb2+ cations are incorporated into a [Cu(l)2Te07] network. PbCu,Te07 can thus be viewed as a lead copper oxocuprate(II) tellurate. Calculations of the Coulomb terms of lattice energy reveal two possible positions for the lone pair of electrons at Pb'+.
