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 .…”

“…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.…”

“…The bond lengths of the carbonyl O1-C5 ¼ 1.273(5) Å ; O2-C16 ¼ 1.267(5) Å and thiocarbonyl S1-C6 ¼ 1.746(4) Å ; S3-C17 ¼ 1.716(5) Å groups were in between those for double and single bonds (Supplementary Table 7). The investigated complex observed same behavior for C-N-C-N bond lengths, which is shorter than the average single C-N bond length of 1.48 Å and greater than average double C ¼ N bond length 1.16 Å , being C5-N1 ¼ 1.310(6) Å , C6-N1 ¼ 1.333(6) Å , C17-N3 ¼ 1.337(6) Å , C16-N3 ¼ 1.325(6) Å , C17-N4 ¼ 1.344(6) Å , C6-N2 ¼ 1.336(5) Å , thus showing variable degree of double and single bond character 15 .…”

“…Thiourea derivatives have been effectively used in organocatalysis 13 and as curing agents for epoxy resins. They also act as versatile ligands, which can coordinate with the metal ions either in mono anionic bidentate or in neutral form 14 via oxygen and sulfur atoms of carbonyl (C¼O) and thiocarbonyl (C¼S) groups 15 . The process of chelation/coordination plays an important role in biological systems 16 .…”

N-(Dibenzylcarbamothioyl)-3-methylbutanamide: Crystal structure, Hirshfeld surfaces and antimicrobial activity

“…These ligands exhibit prevalent coordination systems such as neutral bidentate and monobasic bridging in some complexes [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Since the structural and conformational properties of acyl thioureas has been recognized, the use of transition metal complexes, including acylthiourea ligands, have been expanded in many different fields [9][10][11][12].…”
