Diaquabis(2,4′-bipyridyl-N′)dichloromanganese(II)

Abstract

The Mn atom in the title compound, [MnCl2(C10H8N2)2(H2O)2], occupies a centre of symmetry. The pyridine rings are planar and all bond distances are normal. Bond‐valence calculations show that the Mn—O bond is weaker than both the Mn—N and Mn—Cl bonds. The mol­ecules are held together in the crystal by hydrogen bonds.

Diaquadichloridobis(pyridine-κN)manganese(II)

“…1. The bond length of Mn-N, Mn-O, and Mn-Cl is comparable to those observed in a related crystal structure namely that diaqua-dichloro-bis(1-((2-(2,4-dichlorophenyl)-1,3-dioxalan-2yl)methyl)-4H-1,2,4-triazol-4-yl)-manganese(II) (Kruszynski et al, 2001). The molecule exibits two intermolecular hydrogen bonding (O-H•••Cl) between water molecule coordinated to manganese and a chloride bonded to adjacent manganese center with a distance of 2.281 (15) Å ( Fig.…”
