Crystal structure of cis-copper(II) complex with N-(di-n-propylcarbamothioyl)cyclohexanecarboxamide ligand

摘要

Copper(II) complex, cis-[Cu(L-k~2S,O)2] of N-(di-n-propylcarbamothioyl)cyclohexane carboxamide ligands (HL) has been synthesized and structurally characterized by various spectroscopic techniques and single crystal X-ray diffraction crystallography. The cis-[Cu(L-k~2S,O)2], C_(28)H_(50)CuN4O2S2: Monoclinic, space group P2_1 (no. 14), a = 10.025(2) A, b = 21.724(4) A, c = 14.848(3) A, β = 100.60(3)°, Z = 4, D_(calc)= 1,259 g/cm~3, 22069 reflections measured (5.88° ≤ 20 ≤ 50.2°), 5639 unique (R_(int) = 0.0630, R_(sigma) = 0.0678) which were used in all calculations. The final R1 was 0,0488 (≥2σ(I)) and wRz was 0.1277 (all data). Single crystal analysis revealed that a square-planar coordination geometry is formed around the copper atom by two sulphur and two oxygen atoms of the related ligand, which are in a cis configuration.
