Anionopentaaminecobalt(III) complexes with polyamine ligands 28. The crystal structures of [CoCl(tacn)(en)]ZnCl4, [CoCl(tacn)(ampy)]ZnCl4·H2O, unsym-[CoCl(N-Metacn)(en)]-ZnCl4·H2O, trans-(R,S)-[CoCl(2,2,3-tet)(NH3)]ZnCl4 and unsym-fac-[CoCl(bn)(dien)]ZnCl4
摘要:
The structures of some [CoCl(N)(5)]ZnCl4 . xH(2)O complexes have been determined by single crystal X-ray diffraction. Only one isomeric form is possible for each of [CoCl(tacn) (en)]ZnCl4 (monoclinic P2(1)/c, a = 8.143(2), b = 13.001(2), c = 15.811(2) Angstrom, beta = 97.276(13)degrees, V = 1788.0(48) Angstrom(3), Z = 4) and [CoCl(tacn)(ampy)]ZnCl4 . H2O (monoclinic, Cc, a = 20.682(9), b = 7,730(3), c = 15.599(7), beta = 124.3(4)degrees, V = 2060.33(1.85) Angstrom(3), Z = 4) but [CoCl(N-Metacn) (en)]ZnCl4 . H2O (monoclinic, P2(1)/n, a = 12.4930(10), b = 9.685(3), c = 17.109(2), beta = 109.610(10)degrees, V = 1949.2(7) Angstrom(3), Z = 4) adopts the unsym configuration. [CoCl(dien) (bn)]ZnCl4 (monoclinic, P2(1)/n, a = 14.392(3), b = 7.849(2), c = 15.900(5) Angstrom, beta = 94.78(2)degrees, V = 1789.9(8) Angstrom(3), Z = 4) contains a seven-membered coordinated 1,4-butanediamine ring and the complex adopts the unsym-fac configuration. From the reaction between NH3(aq.) and trans-[CoCl2(2,2,3-tet)](+), conglomerate crystals of trans-(R,S)-[CoCl(2,2,3-tet) (NH3)]ZnCl4 (orthorhombic, P2(1)2(1)2(1) a = 7.579(2), b = 13.196(2), c = 17.407(4) Angstrom, V = 1740.9(6) Angstrom(3), Z = 4) can be isolated.
