Hexakis(N,N′-dimethylthiourea-κS)nickel(II) nitrate

The title complex salt, [Ni(C3H8N2S)6](NO3)2, consists of an [Ni(Dmtu)6]2+ (Dmtu is N,N′-dimethylthiourea) dication and two nitrate counter-anions. The NiII atom (site symmetry overline{3}) is coordinated by the S atoms of six Dmtu ligands within a slightly distorted octahedral environment. The crystal structure is characterized by weak intramolecular N—H...S interactions and by intermolecular N—H...O hydrogen bonds involving the nitrate anion (site symmetry 3.). These intermolecular interactions lead to the formation of two-dimensional networks lying parallel to the ab plane. The networks are linked via non-classical intermolecular C—H...O hydrogen bonds, forming a three-dimensional arrangement.
