A two-dimensional coordination polymer: poly[bis­­[μ2-N-ethyl-N-(pyridin-4-ylmeth­yl)di­thio­carbamato-κ3N:S,S′]cadmium(II)] 3-methyl­pyridine monosolvate]

The title compound, {[Cd(C9H11N2S2)2]·C6H7N}n, features two μ2-κ3-di­thio­carbamate ligands each of which chelates one CdII atom, via the S atoms, while simultaneously bridging to another via the pyridyl-N atom. The result is a two-dimensional coordination polymer extending parallel to the ab plane with square channels along the b axis. The CdII atom geometry is based on a distorted cis-N2S4 octa­hedron. The 3-methyl­pyridine mol­ecules reside in the channels aligned along the b axis, being held in place by methyl­ene-C—H⋯N(3-methyl­pyridine) and (3-methyl­pyridine)-C—H⋯π(pyrid­yl) inter­actions. Pyridyl-C—H⋯S and di­thio­carbamate-methyl-C—H⋯π(pyrid­yl) inter­actions provide connections between layers along the c axis.
