Abstract

The syntheses, structures, and characterization (IR, TGA/DTA) of a family of layered coordination polymers containing Cd2+, bridging anions (SCN- and Cl-), and chelating C2H 6N2O2 methyl carbazate (mc) and C 3H8N2O2 ethyl carbazate (ec) ligands are described, viz: Cd(SCN)2(C2H6N 2O2), Cd(SCN)Cl(C2H6N 2O2), Cd(SCN)2(C3H8N 2O2), and Cd(SCN)Cl(C3H8N 2O2). Single-crystal structures show them to contain distorted CdN3OS2 (for the thiocyanate) and CdN 2OCl2S (for the thiocyanate/chloride) octahedra, in which the mc and ec ligands adopt an N,O-bidentate coordination mode, and the four anions bridge adjacent metal ions, which leads to polymeric sheets built up from double-octahedral layers propagating in the (1 0 0) plane. The topological linkage of the metal ions, which is the same in each structure, can be described as a distorted hexagonal grid. The crystal structures are completed by weak N-HO, N-HN, N-HCl, and N-HS hydrogen bonds, which all occur within the (1 0 0) polyhedral layers.
