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

Abstract

Key indicators: single-crystal X-ray study; T = 223 K; mean (N-C) = 0.003 Å; R factor = 0.029; wR factor = 0.056; data-to-parameter ratio = 15.2.The title complex salt, [Ni(C 3 H 8 N 2 S) 6 ](NO 3 ) 2 , consists of an [Ni(Dmtu) 6 ] 2+ (Dmtu is N,N 0 -dimethylthiourea) dication and two nitrate counter-anions. The Ni II atom (site symmetry 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-HÁ Á ÁS interactions and by intermolecular N-HÁ Á ÁO 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-HÁ Á ÁO hydrogen bonds, forming a three-dimensional arrangement. Related literature ExperimentalCrystal data [Ni(C 3

Dichloridobis(thiourea-κS)nickel(II)

“…In our case, the coordination complexes of Ni (II) salts with thiourea show a variety of compositions and types of coordination (octahedral, tetragonal, square-planar and tetrahedral) (Asif et al 2010). In general, the predominant coordination geometries for the Ni (II) -Ligand-X (X= Cl -, Brand I -) are Tetragonal (Ni (II)…”

Syntheses and structural characterization of divalent metal complexes (Co, Ni, Pd and Zn) of sterically hindered thiourea ligand and a theoretical insight of their interaction with SARS-CoV-2 enzyme

“…In contrast to predominant tetrahedral arrangement around Co the situation for the analogous Ni II compounds is more complicated as it can adopt octahedral, tetrahedral or square planar geometries with thiourea ligands [ 17 , [57] , [58] , [59] , [60] , [61] , [62] , [63] , [64] , [65] , [66] , [67] ]. In solvate free complex 2 , nickel is located on two fold symmetry axis with pseudo-tetrahedral geometry ( Figure 4 ).…”
