ZnII/NiII coordination polymers with 2-phenylsuccinate and 1,3-bis(4-pyridyl)propane

Two coordination polymers, [ZnCl(PHSU)(0.5)(bpp)](n) (1) and [Ni-3(PHSU)(3)(bpp)(2)(H2O)(2)](n) (2) (PHSU = 2-phenylsuccinate, bpp = 1,3-bis(4-pyridyl)propane), have been synthesized by hydrothermal reactions of ZnCl2 or NiCl2 center dot 6H(2)O with PHSU2- and bpp. Single-crystal X-ray diffractions reveal that 1 is a 1-D coordination ladder with tetrahedral Zn-II, which is further linked into a 2-D network by hydrogen bonds. Complex 2 displays a 2-D coordination network with (4, 4) topology containing octahedral Ni-II with linear trinuclear Ni-3(II) clusters. Flexible PHSU2- in 1 and 2 adopts different coordination modes. Thermogravimetric analysis, powder X-ray diffraction, EA, and IR of 1 and 2 were also investigated.
