A binuclear iminodiacetato-copper(II) complex with the N,N'-bis(pyridine-4-ylmethylene)hydrazine ligand as spacer
MetadataShow full item record
The centrosymmetric title compound, -N,N'-bis(pyridin-4-ylmethylene)hydrazine-bis[diaqua(iminodiacetato)copper(II)], [Cu2(C4H5NO4)2(C12H10N4)(H2O)4], features a trans-N2O4 donor set that defines a heavily distorted octahedral geometry. Coordination is provided by a tridentate iminodiacetate (ida) dianion, one end of a bidentate bridging N,N'-bis(pyridin-4-ylmethylene)hydrazine ligand, which is disposed about a centre of inversion, and two water molecules. Extensive hydrogen bonding leads to a cohesive crystal structure.
