[Delta]-Aqua-S-citrato(2-)manganese(II)

Y.-F. Deng, Z.-H. Zhou, H.-L. Wan and S. W. Ng

Abstract: The citrato(2-) ligand in aquacitrato(2-)manganese(II), [Mn(C6H6O7)(H2O)], chelates the Mn atom through the [alpha]-hydroxyl, the [alpha]-carboxyl and one [beta]-carboxyl O atom, while the other [beta]-carboxylic acid group remains uncoordinated. Each O atom of the [alpha]-carboxyl groups is bonded to an adjacent Mn atom, leading to octahedral Mn and a helical chain. Neighboring chains are consolidated into a tightly held crystal structure by hydrogen bonds.
