Crystal structure of dichloridobis(1,3-diazinane-2-thione-κS)cadmium

Abstract

In di­chlorido­bis­(1,3-diazinane-2-thione-κS)cadmium(II), the CdII atom is bound to two chloride anions and two thione ligands via their S atoms. The geometry around the CdII atom is distorted tetra­hedral, with the bond angles in the range 101.61 (3)–118.00 (3)°. Intra­molecular N—H⋯Cl hydrogen-bonding inter­actions stabilize a butterfly syn mol­ecular conformation.

2D polymeric cadmium(II) complexes containing 1,3-imidazolidine-2-thione (Imt) ligand, [Cd(Imt)(H 2 O) 2 (SO 4 )] n and [Cd(Imt) 2 (N 3 ) 2 ] n

“…Cadmium(II) is known to form a wide variety of 1:1 to 1:4 complexes with thiones (L), with the structural arrangements generally based on tetrahedral and octahedral coordination environments. The 1:1 complexes [1][2][3][4] [11,12] (X = Cl, Br, I) are the most common and often consist of discrete monomeric molecules with a tetrahedrally [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] (or octahedrally [22,23]) coordinated Cd(II) ion. In some cases, polymeric species are formed through bridging sulfur or nitrogen atoms [21,[24][25][26][27][28][29], e.g., [Cd(Metu) 2 (SCN) 2 ] n [24] and [Cd(Imt) 2 (SCN) 2 ] n [25].…”

“…These structural studies show that thioureas or thiones coordinate to cadmium(II) via the sulfur atom. We have reported earlier the crystal structures of several cadmium(II) complexes of heterocyclic thiones [4,[5][6][7][8][9][10][14][15][16][17]23,24,[33][34][35]. To investigate further about the structural aspects of such complexes, we report in this work the spectroscopic data and the X-ray structures of two new 2D polymeric (2).…”
