In-situ hydrothermal preparation of a novel 3D CuI-based tetrazole coordination polymer with pseudo-porphyrin secondary building units

A novel 3D CuI-based tetrazole coordination polymer through the employment of in-situ hydrothermal techniques by using 4-cyanopyridine, NaN3 and CuI, [Cu5(L)3I2] (1) (HL = 5-(4-Pyridyl)-1H-tetrazole) has been synthesized and structurally characterized by X-ray single-crystal diffraction as well as by powder X-ray diffraction, elemental analysis and thermogravimetric analysis. In compound 1, each CuN3I tetrahedron, CuN2I2 tetrahedron and CuN3 triangle are linked to each other by L ligand to form a 3D framework structure. It is interesting to note that the interconnection of Cu1 and Cu2 ions by bridging L ligand form pseudo-porphyrin secondary building units. Surface photovoltage, field-induced surface photovoltage and luminescent properties of compound 1 have also been studied.
