description

In the X-ray crystal structure of the title complex, [Ni(C(4)H(13)N(3))(2)](C(2)H(3)N(4)O(2)S(2))Cl.H(2)O, the coordination polyhedron is composed of non-centrosymmetric [Ni(diethylenetriamine)(2)](2+) cations in which the triamine ligands coordinate to the metal centre as tridentate ligands in a facial position. The Ni(II) ions are linked to six N atoms in an octahedral arrangement, slightly compressed in one extreme. The sulfonamide behaves as a counter-ion instead of as a ligand. Important information about the deprotonated sulfonamide group conformation has been obtained.
