All these compounds were structurally characterized by single-crystal and powder X-ray diffraction technique, in which complexes 3, 5 and 6 are 2D structures, and complexes 1, 2 and 4 are 3D structures. Their thermal stabilities and photoluminescence behaviors have also been investigated, in which complexes 1, 3 and 4 appear phase transformation after heating, and they are irreversible process.
