Özet

The structures of trans-bis[2-(aminomethyl) pyridine-kappa(2)N,N']bis(saccharinato-kappaN) zinc(II), [Zn(C7H4NO3S)(2)(C6H8N2)(2)], (I), and [2-(aminoethyl) pyridine-kappa2N,N'] bis(saccharinato-kappaN)zinc(II), [Zn(C7H4NO3S)(2)(C7H10N2)], (II), exhibit octa-and tetrahedrally coordinated Zn-II atoms, respectively. The diamine ligands behave as N,N'-bidentate ligands, while saccharinate (sac) is coordinated through the N atom. In (I), the complex lies about an inversion centre with the Zn atom disordered and displaced by 0.256 (2) Angstrom from a centre of symmetry towards a sac N atom. The crystal structure of (I) is stabilized by N-H...O hydrogen bonds and the crystal packing of (II) is determined by hydrogen bonding as well as weak pi-pi stacking interactions between the sac ligands.
