Crystal and molecular structure of bis(4-bromo-N-(di-n-butylcarbamothioyl)benzamido) copper(II) complex

Metal based drugs: design, synthesis and in-vitro antimicrobial screening of Co(II), Ni(II), Cu(II) and Zn(II) complexes with some new carboxamide derived compounds: crystal structures of N-[ethyl(propan-2-yl)carbamothioyl]thiophene-2-carboxamide and its copper(II) complex

“…The structure of Cu(L 1 ) 2 complex showed the bond lengths and angles 15 as expected. The Cu(L 1 ) 2 complex existed as a monomer unit in which each copper Cu1 atom was coordinated with each oxygen and each sulfur of two ligands (Figure 2) in a cis-fashion, with slightly distorted square planar geometry 15 .…”

In both chelate rings, the distances of N1-C6 (1.333(6) Å ) and N3-C17 (1.337(6) Å ) in the thiourea fragment were almost same, but the distances of N1-C5 (1.310(6) Å ) and N3-C16 (1.325(6) Å ) (Supplementary Table 8) were slightly different, which supported the distorted square planar geometry of the complex.…”

Synthesis and Characterization of Novel Thiourea Derivatives and Their Nickel and Copper Complexes

“…The distance of nickel atom from the best plane through the coordination sphere is 0.029Å. The bond lengths of the carbonyl and thiocarbonyl groups lie between those for double and single bonds, a feature which is known from related structures (O1-C8: 1.271(8)Å; O2-C22: 1.271(7)Å; S1-C1: 1.729(7)Å; S2-C15: 1.745(7)Å) [11,12,21,22,40,41] (Table 3). The bond length C1-N2 is 1.342 (8) and N(2)-C(8) 1.340(8)Å.…”

Crystal and molecular structure of bis(N-(diethylcarbamothioyl)cyclohexane carboxamido)copper(II) complex

“…The six-membered rings are formed via oxygen and sulphur atoms, and the dihedral angle between these chelate rings in the copper complex is 44.96° ( Figure 2). The bond angles around the copper ion are S1-Cu1-O1 = 95.97(5)° and S1 i -Cu1-S1 = 92.94(4)° ( i -x, +y, 1-z) for cis-[CuL2], so the bite angles of the complex deviate slightly from the ideal angle (90°) [69]. The copper center, surrounded by oxygen and sulphur atoms in the complex form, has a distorted square planar geometry as shown in Figure 1.…”
