Tetrakis(N-methylthiourea-κS)copper(I) iodide

Abstract

Key indicators: single-crystal X-ray study; T = 100 K; mean (N-C) = 0.002 Å; R factor = 0.034; wR factor = 0.085; data-to-parameter ratio = 37.4.In the title complex, [Cu(C 2 H 6 N 2 S) 4 ]I, the Cu I atom lies on a " 4 4 axis. Each Cu I centre binds to the S atoms of four Nmethylthiourea ligands in a distorted tetrahedral environment. In the crystal structure, intermolecular N-HÁ Á ÁS and N-HÁ Á ÁI hydrogen bonds, together with weak C-HÁ Á ÁN interactions, link the cations and anions into a threedimensional network. metal-organic compounds m2384 # 2007 International Union of Crystallography

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

“…2, illustrating that a nearly ''square planar'' setup is formed. Such an involvement of counter ions in hydrogen bonding with the coordinated ligands has also been observed in [Cu(Metu) 4 ]Cl and [Cu(Metu) 4 ]I [4,20]. Thereby, in 1, only the hydrogen atoms at the secondary amine function, that is, N2 and H3 N as well as symmetry generated equivalents, are involved, cf.…”

“…cations with crystallographically imposed D4 symmetry and uncoordinated Br -ions. The complex is monomeric 4 ]I, which have been reported previously [4,20]. Within the crystal package, a 3-D supramolecular structure is generated via a regular pattern of hydrogen bonds between [Cu(Metu) 4 ] ?…”

“…Some reports are also available on the antimicrobial activities of copper(I)-thione complexes [11,12]. We have been investigating the spectral and structural chemistry of coinage metal complexes of thiones in order to study their physical properties, the stereochemistry of the metal atoms, and the coordination modes adopted by the ligands [4,5,[19][20][21][22][34][35][36][37][38][39][40]. Here, we report on the synthesis, characterization, and antimicrobial properties of a number of copper(I) bromide complexes of thioureas.…”

Synthesis and characterization of silver(I) complexes of thioureas and thiocyanate: crystal structure of polymeric (1,3-diazinane-2-thione)thiocyanato silver(I)

“…Our interest in these ligands is because of their relevance to biological systems [3,4], and consequently, we have been investigating the coordination chemistry of > C = S ligands with d 10 metal ions in an attempt to assess their modes of binding and to study their physical properties [10][11][12][13][14][15][16][17][18]. Several complexes of thiones with silver cyanide have been prepared and characterized using NMR spectroscopy and X-ray crystallography.…”

“…The complexation of thiones towards metal ions such as copper(I) and silver(I) has received considerable importance in view of their variable bonding modes, structural diversity, and promising biological implications [1][2][3][4][5][6][7][8][9][10]. Our interest in these ligands is because of their relevance to biological systems [3,4], and consequently, we have been investigating the coordination chemistry of > C = S ligands with d 10 metal ions in an attempt to assess their modes of binding and to study their physical properties [10][11][12][13][14][15][16][17][18].…”
