Mixed-Ligand Complexes [Cd(DMSO)_5(NCS)][Cr(NH_3)_2(NCS)_4] centre dot 3DMSO and [Mn(DMSO)_4(H_2O)_2][Cr(NH_3)_2(NCS)_4]_2 centre dot 6DMSO centre dot 2H_2O: Syntheses and Crystal Structures

摘要

New mixed-ligand coordination compounds[Cd(DMSO)_5(NCS)][Cr(NH_3)_2(NCS)_4] centre dot 3DMSO (I) and [Mn(DMSO)_4 (H_2O)_2][Cr(NH_3)_2(NCS)_4]_2 centre dot 6DMSO centre dot 2H_2O (II) have been synthesized and studied by IR spectroscopy and X-ray diffraction analysis. The crystals of compound I are monoclinic, a = 14.5275(7), b = 23.1692(11), c = 14.6969(6) A, P = 97.057(2) deg, V= 4909.4(4) A~3, space group P2_(1/c), Z = 4, phi_(calcd) = 1.507 g/cm~3, R = 0.0556. The crystals of compound II are triclinic, a = 11.7784(3), b = 12.1760(3), c = 13.1922(2) A, alpha = 85.5420(10) deg, beta = 87.9000(10) deg, gamma = 70.3680(10) deg, V= 1776.46(7) A~3, space group P1, Z= 1, phi_(calcd) = 1.444 g/cm~3, R = 0.0350.
