Structural characterization of dichloridobis(N,N’-dimethylthiourea-S)cadmium(II)

Synthesis and Crystal Structures of Cadmium Iodide Complexes of N,N′-Diethylthiourea and 1,3-Diazinane-2-thione

“…In both complexes, the Cd-S and Cd-I bond lengths (Table 3) are in agreement with those reported for related compounds [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. The SCN 2 moieties are essentially planar with bond lengths corresponding to values intermediate between single and double bonds.…”

“…In view of this, cadmium(II) complexes of thiones have been widely studied in recent years [8][9][10][11][12][13][14][15][16]. The structural studies on cadmium(II) halide complexes of thiones describe that in most of the cases the structures consist of discrete mononmeric molecules with cadmium adopting a somewhat distorted tetrahedral coordination geometry [11][12][13][14][15][16][17][18][19][20][21][22][23]. In some cases, polymeric structures are obtained through sulfur and halide bridging consisting of [CdS 3 X 3 ] distorted octahedra [18,19].…”

“…Our interest lies in understanding various spectral and structural features of these complexes and their relation to bonding and other physicochemical properties. Consequently, we have recently reported the crystal structures of several cadmium(II) complexes of thioamides of the type [CdL 2 X 2 ], where L = thiourea, N,N 0 -dimethylthiourea or N,N,N 0 ,N 0 -tetramethylthiourea, and X is Cl, Br, I or CN [10][11][12][13][14]. The present investigation deals with the spectroscopic characterization and crystal structures of two cadmium(II) iodide complexes with N,N 0 -diethylthiourea (Detu) and 1,3-diazinane-2-thione (Diaz) as ligands.…”

Synthesis, characterization, and antibacterial activities of copper(I) bromide complexes of thioureas: X-ray structure of [Cu(Metu)4]Br

“…In the 13 C NMR spectrum, the [C=S resonance of the ligands in the respective copper complexes is shifted upfield by about 4-13 ppm as compared to the free positions in accordance with the data observed for other complexes of d 10 metals with thiones [6,[34][35][36][37][38][39][40][45][46][47][48]. The upfield shift is attributed to the lowering of the [C=S bond order and a shift of N ?…”

Synthesis and structural characterization of cadmium(II) complexes of tetramethylthiourea (Tmtu); X-ray structure of [Cd(Tmtu)2Cl2]

“…The interest in cadmium(II) complexes of thiourea type ligands also arises because of their semiconducting and non linear optical properties [13,14]. Cadmium(II) is known to form a wide variety of 1 : 2 complexes with thiones (L) of the type, L 2 CdX 2 (where X is a halide or pseudoha lide), with structural arrangements entirely based on tetrahedral (somewhat distorted) environment [15][16][17][18][19][20][21][22][23][24][25][26][27]. In view of our interest on d 10 1 The article is published in the original.…”
