Hexakis(N,N'-dimethylthiourea-S)nickel(II) nitrate

Abstract: 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 Ni^II 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-HS interactions and by intermolecular N-HO 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-HO hydrogen bonds, forming a three-dimensional arrangement.
