Abstract
The detailed X-ray structural elucidation of reaction products of a zinc(II) salt with O,O′-dialkyldithiophosphate and nitrogen-containing heterocycles (N–N=1,10-phenanthroline (phen) or 2,2′-bipyridine (bpy)) has been performed. Surprisingly, together with [Zn(S2 P(OR)2)2(N–N)] compounds, also ionic-type complexes having the formula of [Zn(N–N)3](S2 P(OR)2)2 have been obtained using the same molar ratios of the reactants. The prepared complexes have been characterized by elemental analysis and single-crystal X-ray analysis. The crystallographic analysis showed that the bond lengths and bite angles of the prepared complexes are in good agreement with those of similar compounds. The crystal packing of described complexes is formed via π–π stacking interactions and/or C–H···S non-covalent contacts.
