[N,N'-Bis(3-aminopropyl)ethylenediamine]Disaccharinatocadmium(II) 0.25-Hydrate

Abstract

The asymmetric unit of the title compound, [Cd(C7H4NO3S)2(C8H22N4)] ·0.25H2O, consists of two [Cd(sac)2(paen)] mol-ecules [sac is saccharinate (C7H4NO3S) and paen is N,N′-bis-(3-propyl-amine)ethyl- enediamine (C8H22N4)], and a partial- occupancy water mol-ecule. Each Cd II ion is octa-hedrally coordinated. The equatorial plane of the octa-hedron is formed by N atoms of the paen ligands, and the axial positions are occupied by the N atoms of the sac ligands. In one of the mol-ecules, the sulfonyl group of a sac ligand is disordered over two different orientations, with site-occupancy factors of 0.83 and 0.17. N - H⋯O hydrogen bonding is observed between the independent mol-ecules. Neighbouring [Cd(sac)2(paen)] units are linked by N - H⋯O hydrogen bonds into chains running parallel to the a axis. © International Union of Crystallography 2007.
