Poly[bis(N‐methylformamide)tetra‐μ‐thiocyanato‐manganese(II)mercury(II)]

The title complex, [MnHg(NCS)₄(C₂H₅NO)₂]_n, consists of slightly distorted MnN₄O₂ octa­hedra and HgS₄ tetra­hedra. Each Mn^II cation is bound to four N atoms of the NCS groups and two O atoms of the N‐methyl­formamide (NMF) ligands in a cis configuration. Each Hg^II cation is coordinated to four S atoms of NCS groups. Each pair of Mn^II and Hg^II cations is connected by an –NCS– bridge, forming an infinite three‐dimensional –Mn—NCS—Hg– network.
