Bis(saccharinato-N)zinc(II) complexes with N,N'-bidentate 2-aminomethylpyridine and 2-aminoethylpyridine

Abstract: The structures of trans-bis[2-(aminomethyl)pyridine- [bold kappa] ²N,N']bis(saccharinato-N)zinc(II), [Zn(C₇H₄NO₃S)₂(C₆H₈N₂)₂], (I), and [2-(aminoethyl)pyridine-²N,N']bis(saccharinato-N)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) Å from a centre of symmetry towards a sac N atom. The crystal structure of (I) is stabilized by N-HO hydrogen bonds and the crystal packing of (II) is determined by hydrogen bonding as well as weak [bold pi] - stacking interactions between the sac ligands.

Formula: [Zn(C₇H₄NO₃S)₂(C₆H₈N₂)₂] and [Zn(C₇H₄NO₃S)₂(C₇H₁₀N₂)]
