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

Abstract: Copper(II) complex, cis-[Cu(L-κ 2 S,O)2] of N-(di-n-propylcarbamothioyl)cyclohexanecarboxamide ligands (HL) has been synthesized and structurally characterized by various spectroscopic techniques and single crystal X-ray diffraction crystallography. The cis-[Cu(L-κ 2 S,O)2], C28H50CuN4O2S2: Monoclinic, space group P21/n (no. 14), a = 10.025(2) Å, b = 21.724(4) Å, c = 14.848(3) Å, β = 100.60(3)°, Z = 4, Dcalc = 1.259 g/cm 3 , 22069 reflections measured (5.88° ≤ 2Θ ≤ 50.2°), 5639 unique (Rint = 0.0630, Rsigma = … Show more

“…The ] C=O stretching vibration can be observed in the ligand at 1695 cm −1 , and the ] CO stretching vibration of the corresponding Ni(II) and Cu(II) complexes appears at 1445 and 1493 cm −1 , respectively. This is in close agreement with other previously studied thiourea derivatives [18,19,29,[32][33][34][35].…”

“…In the 1 H NMR spectra, the N-H signal present in the ligand at 8.58 ppm disappears in the complexes. The aryl proton signals are shifted to lower field [18,19,29,[32][33][34][35]. ∘ and 85.97(6) ∘ (Ni and Cu).…”

“…This result was also confirmed by the short C-N bond distance (N1-C5, 1.345(3) and N1-C6, 1.322(3) Å) which are shorter than the average for C-N single bond distance (1.48 Å) [71,72]. The molecular structure is very close to the related bis(N-(di-n-propylcarbamothioyl)cyclohexanecarboxamido) copper(II) complex, [71] and shows similar short Metal-S, Metal-O, C-O, C-N and C-S bonds indicating the known πbonding character in the chelate rings. All other bond lengths are within normal ranges (Table 2) [72].…”
