Abstract

Reaction of Zn(NO3)2·6H2O with the bent bridging ligand 4,4′-dithiodipyridine (dtdp), showing axial chirality, in the presence of the chelating 1,10-phenanthroline (phen) ligand in ethanol yielded [{Zn(μ-dtdp)2(H2O)2}(NO3)2·2C2H5OH·2H2O]n (1). In 1, Zn2+ ions are linked by two dtdp ligands of opposite chirality into a one-dimensional coordination polymer of the repeated-rhomboid type; the phen co-ligand was not encountered in the crystal. Pseudo-symmetry of the lattice is discussed for 1. Reaction of Zn(NO3)2·6H2O and dtdp in an ethanol/water mixture in absence of phen led to the known repeated-rhomboid coordination polymer [{Zn(NO3)(μ-dtdp)2(H2O)}NO3·4H2O]n (2), the crystal structure of which was redetermined at 110 K. At low temperature, the nitrato-κO ligand in one axial position of Zn2+ was found to be non-disordered as distinct from the room temperature structure (Horikoshi and Mikuriya, Cryst Growth Des 5:223–230, 2005). The Zn2+ ions in 2 are joined by two dtdp ligands of the same chirality.
