Polymeric bis( N-methyl­form­amide)­tetra­thiocyanato­cadmium(II)­mercury(II).

The title complex, poly­[bis( N-methyl­form­amide)­tetra-μ-thio­cyanatocadmium(II)­mercury(II)], [CdHg(NCS)4(C2H5NO)2] n, contains slightly distorted octahedral CdN4O2 and tetrahedral HgS4. The CdII atom is coordinated by the N atoms of four SCN groups and O atoms of two N-methyl­form­amide ligands in a cis orientation. The HgII atom is coordinated by S atoms of one independent and three symmetry-related SCN groups. The two metal atoms, viz. CdII and HgII, are connected by an —S=C=N— bridge, forming an infinite three-dimensional network. [ABSTRACT FROM AUTHOR]
