Abstract

Three novel complexes, ZnCl~2~(H~2~O)(POPOP)·POPOP) (1), [ZnCl~2~(POPOP)]~n~ (2), and {Zn~2~(CH~3~COO)(POPOP)~1.5~Cl~3~}~n~ (3) {POPOP = 1,4‐bis[2‐(5‐phenyloxazolyl)]benzene}, of zinc−POPOP coordination polymers have been obtained from an identical starting mixture using temperature as the only independent variable. Complexes 1−3 all crystallize in the triclinic P$\bar 1$
space group, but their Zn^II^ centers adopt different coordinations. Complex 1 consists of POPOP‐coordinated zinc units and discrete POPOP molecules, 2 features an interesting zigzag chain structure, and 3 consists of unique ladder‐like double‐chains bridged by POPOP units. Furthermore, 1−3 display some different fluorescent emissions based on their different coordination architectures. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
