 Title    Die Kristallstruktur von Calciumhexacyanoferrat(II)- Hexamethylentetramin-Wasser(l/l/6) Ca 2 [Fe(CN) 6 ] * C 6 H 12 N 4 * 6 H 2 0 The Crystal Structure of Calciumhexacyanoferrate(II)- Hexamethylenetetramine-Water(l/l/6) Ca 2 [Fe(CN) 6 ] * C 6 H 12 N 4 * 6 H : 0  
 Abstract    Ca 2 [Fe(CN) 6 ] • C t ,H 1 2N 4 -6H 2 0 crystallizes in the monoclinic space group B2lb with a = 1130,2(4), b = 1373,5(4), c = 1353,0(4) pm and y = 97,17°. The X-ray single crystal structure determination converged at R -0.055 (2057 reflections). Each of the four Fe(CN) 6 octahedra (Z = 4) in the unit cell is coordinated by six Ca atoms with mean N CY AN — Ca distances of 253.5(3) pm. The Ca atoms are bridged by hexamethylenetetramine and water molecules.

 Title    Die Kristallstruktur von Hexa- The Crystal Structure of Hexa-^-chloro-/^- oxo-tetrakis [hexamethylenetetraminecopper- (II)], [Cu4Cl60(C6H12Nl)4], a Copper(II) Complex with a Structure Related to that of Beryllium Oxoacetate  
 Abstract    -tetrakis [hexamethy lentetramin -kupfer(II)], [CU4C160(C6H12N4)4], einem Kupfer(II)-Komplex mit Berylliumoxoace-tat-ähnlicher Struktur By reaction of solutions of CuCl2 • 2H20 and hexamethylenetetramine, C6H12N4, in acetone, a complex [Cu4Cl60(C6Hi2N4)] could be ob-tained as single crystals. An X-ray analysis shows that the complex has a structure related to that of basic beryllium acetate. An oxygen atom is tetrahedrally surrounded by four cop-per atoms which, together with six chlorine atoms, form an adamantane-like core. Each copper atom is bonded via a nitrogen atom to a hexamethylenetetramine molecule.

 Title    Metallkomplexe mit Hexamethylentetramin als Ligand, VI [1] Kristallstruktur von Bis-hexamethylentetramin-bisisocyanatokupfer(II), [CU(NCO)2(C6H12N4)2]  
 Abstract    Crystals of the complex [Cu(NCO)2(C6Hi2N4)2] could be obtained by reaction of copper-(Il)nitrate, hexamethylenetetramine, and KNCO in CHCI3 as a solvent. The crystals are triclinic, space group Cl, Z = 4, a = 1373.1(9), b = 2083.1(9), c = 642.6(3) pm, a = 91.05(4), ß = 90.54(6), y = 107.39(6)°. The copper atom is bonded to two terminal cyanato groups via the nitrogen atoms, and to two liexamethylentetramine molecules. In the solid state the coordination of the copper atom is, however, tetragonal pyramidal, because there is an additional, rather long bond to one of the hexamethylenetetramine molecules of the neighbouring complex unit, resulting in the formation of chains.

 Title    Metal Complexes with Hexamethylenetetramine as a Ligand, V II [1] Crystal Structures of the Zinc Chloride Adduct ZnC l2 * C6H 12N4, and the Zinc Bromide Adduct ZnBr2 * C6H 12N4  
 Abstract    By reaction of zinc chloride and zinc bromide with hexamethylenetetramine in water/methanol crystals of the adducts Z nC l2 • C6H 12N 4 and ZnBr2 • C6H I2N4, resp. were obtained. The compounds are isotypic, they crystallize in the orthorhombic space group P2,am (non-standard setting of space group Pmc2,, No. 26), Z = 2. The lattice parameters of the zinc chloride adduct are a = 1168.0(4), b = 685.7(4), and c = 601.1(4) pm, of the zinc bromide adduct a — 1188.9(6), b = 721.5(5), and c = 602.3(4) pm. The adducts are polymeric, they form parallel chains in the crystal. The zinc atoms are bonded to two halo­ gen atoms and, via nitrogen atoms, to two hexa­ methylenetetramine molecules, which act as biden-tate ligands. The coordination of the zinc atoms is approximately tetrahedral.
