Dihistaminedisaccharinatonickel(II)

Abstract

The title complex, bis[2-(1H-imidazol-4-yl)ethanamine]disaccharinatonickel(II), [ Ni( C7H4NO3S) 2( C5H9N3) 2], has an octahedral coordination around the nickel(II) ion, and the Ni atom lies on a center of symmetry. The histamine ligands and sulfonyl group of the saccharinate ligands show disorder, and the two conformations (A and B, with almost equal occupancy) are inversion isomers. The molecular packing is stabilized by intra- and intermolecular hydrogen bonds between imidazole N atoms and sulfonyl O atoms. In the extended stucture, intermolecular N-H center dot center dot center dot O hydogen bonds constitute a chain structure parallel to the direction [110].
