摘要：
Complexes Zn(H2O)4(L) (I) and Zn(H2O)(L) (II) (H2L = p-HOOCC6F4COOH) are synthesized. Single crystals of compound [Zn(H2O)4(L) · 4H2O]n (III) are grown. According to the X-ray diffraction data, the crystal structure of compound III is built of zigzag chains of coordination polymer Zn(H2O)4(L) and molecules of water of crystallization. The chain contains ions Zn2+, whose octahedral coordination sphere includes the O atoms of four water molecules and two O atoms of the deprotonated carboxyl groups. The chains in structure III are joined by a system of hydrogen bonds of coordinated water molecules and molecules of water of crystallization. The photoluminescence spectrum of H2L exhibits the band with λmax = 368 nm. The spectra of compounds III, I, and II contain bands at 322, 340, and 353 nm, respectively.
