Bis(2,2′-bipyridineN,N′-dioxide)bis(tricyanomethanido)manganese(II)

Abstract

In the title complex, [Mn(C4N3)2(C10H8N2O2)2], the MnII atom lies on an inversion center and is coordinated by two 2,2′-bipyridine N,N′-dioxide (dpdo) mol­ecules and two tricyano­methanide (tcm) ligands to form a distorted octa­hedral geometry. Weak inter­molecular C—H⋯O or C—H⋯N hydrogen bonds, involving either the O atom of the dpdo mol­ecule and the pyridyl H atom, or the N atom of the tcm anion and the pyridyl H atom, result in the formation of a three-dimensional network structure.

“…Interestingly, two solvate water molecules are observed and the situation is different from the similar manganese complex reported in which no water molecules were found (Luo et al, 2009). In the title compound, these water The Co-O(dpdo) distances are in the range 2.050 (1)Å -2.070 (1) Å, these values are comparable to the corresponding distances in cobalt-nitroxide complexes (Zhang et al, 2010) and in the Co(dpdo) 2 (H 2 O) 2 (Su & Lan, 2007).…”

“…Recently, several copper tcm complexes with nitrogen-containing heterocyclic co-ligands has been characterized (Yuste et al, 2008(Yuste et al, , 2007. On the other hand, 2,2′-dipyridyl N,N′-dioxide (dpdo) is a new coligand and has two potential oxygen donor atoms, however, few tcm complex with dpdo co-ligand has been reported (Luo et al, 2009). During our systematic investigation of the nature of dpdo co-ligand on the structures and properties of tcm complexes, we obtained a new tcm complex Co(dpdo) 2 (C 4 N 3 ) 2 (H 2 O) 2 (I), we herein report the synthesis and crystal structure of the complex.…”
