Aqua(4-bromobenzoato-κO)bis(1,10-phenanthroline-κ²N,N′)manganese(II) 4-bromobenzoate dihydrate

Abstract

+ complex cation, a 4-bromobenzoate anion and two lattice water molecules. In the complex cation, the Mn II atom is coordinated by four N atoms from two bidentate chelating 1,10-phenanthroline (phen) ligands and two O atoms, one from a 4-bromobenzoate anion and the other from a coordinating water molecule. This completes an MnN 4 O 2 coordination sphere with a distorted octahedral geometry. The Br atom of the bromobenzoato ligand is equally disordered over two sites. In the crystal, the complex cations are connected to each other via O-HÁ Á ÁO, O-HÁ Á ÁBr and C-HÁ Á ÁO hydrogen bonds and -stacking interactions [closest separation = 3.492 (4) Å ]. -contacts [closest separation = 3.771 (4) Å ] also link the complex cations to both the coordinated and non-coordinating 4-bromobenzoate anions. Overall, these contacts generate a three-dimensional network structure. Structure description
