Diaqua­Bis­(4-Bromo­Benzoato-Κo)Bis­(N,N-Diethyl­Nicotinamide-Κn1)Manganese(Ii)

Abstract

In the crystal structure of the title MnII complex, [Mn(C7H4BrO2)2(C10H14N2O)2(H2O)2], the MnII cation is located on an inversion center and coordinated by two diethyl­nicotinamide (DENA) ligands, two 4-bromo­benzoate (PBB) anions and two water mol­ecules in a distorted octa­hedral geometry. The dihedral angle between the carboxyl­ate group and the adjacent benzene ring is 3.25 (14)°. In the mol­ecule, the pyridine ring and the benzene ring are oriented at a dihedral angle of 77.24 (5)°. In the crystal, inter­molecular C—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional network. Weak inter­molecular C—H⋯O hydrogen bonds and π–π inter­actions between the pyridine rings of neighbouring mol­ecules [centroid–centroid distance = 3.537 (1) Å] further consolidate the crystal packing.
