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)
