Abstract
Two novel Zn and Cu complexes with 5-chlorhydroxybenzoate and imidazole ligands, C_{41}H_{36}Zn_2N_8O_{13}Cl_4 (1) and C_{26}H_{22}Cl_2Cu_2N_8O_6 (2), were prepared by slow evaporation method. Single crystal X-ray diffraction analysis was used to determine their structures. The purity of the complexes was confirmed by powder X-ray diffraction analysis. In 1 the Zn^{2+} cation is tetracoordinated with 2 nitrogen atoms from 2 imidazoles and 2 oxygen atoms from the 2 carboxyl groups in 5-chlorhydroxybenzoate. In 2 the coordination polyhedrons of Cu^{2+} center can be described as distorted square pyramidal geometry sharing common edges, with an oxygen atom on the top of the pyramid. The hydrogen bonds and \pi-\pi interactions between the 2 ligands contribute to the presence of the infinite one-dimensional chain in the structure. Furthermore, solid-state fluorescence spectra indicate that both complexes show violet-blue fluorescence and can be potentially used as violet-blue fluorescence materials.
