Aqua[bis(5-bromosalicylidene)ethylenediaminato]chloromanganese(III)

Abstract

The title compound (systematic name: aqua{4,4′‐di­bromo‐2,2′‐[1,2‐ethanediyl­bis­(nitrilo­methyl­idyne)]­diphenolato]­chloro­manganese(III)), [Mn(C16H12Br2N2O2)Cl(H2O)] or [Mn(Br2salen)Cl(H2O)], was prepared from a methanol solution. The Mn3+ ion displays an elongated octahedral geometry, coordinated by two N and two O atoms from salen, one O atom from the water ligand and one Cl− anion, and is slightly displaced out of the Schiff base N2O2 plane toward the axial Cl− ion. Hydro­gen bonds between the coordinated water O and Cl atoms link pairs of mol­ecules into a three‐dimensional network.

“…Mn-O = 1.872 (12) Å] (Dang et al, 2005). The Mn-Cl bond length of 2.2276 (7) %A in the title complex is obviously shorter than those in [Mn(salen)Cl(H 2 O)].H 2 O (salen = N,N′-bis-(salicylideneiminato)ethylene) (2.584 (12) %A)(Panja et al, 2003), [MnCl(salen)(H 2 O)] (salen = 2,2′-[1,2-ethanediylbis-(nitrilomethylidyne)]-diphenolato) (2.468 (2) Å)(Martínez et al, 2002), and [Mn(L)Cl] (L = N,N′-bis{4-(diethylamino)salicylideneiminato}cyclohexane) (2.386 (2) Å)(Dang et al, 2005). The basal bond angles are all approximately close to 90° [O(1)-Mn(1)-O(2), O(1)-Mn(1)-N(1) and O(2)-Mn(1)-N(2) are 91.48 (6)°, 87.99 (6)° and 87.68 (6)°, respectively] except N(1)-Mn(1)-N(2) (76.74 (6)°) which is large smaller than expected(Pecoraro & Butler, Acta Cryst.…”
