Abstract

A new organic–inorganic hybrid chain-like zincoborate [Zn(dap)3][Zn(dap)B5O8(OH)2]2 (1, dap = 1,2-diaminopropane) has been made under solvothermal conditions. The structure was determined by single crystal X-ray diffraction and further characterized by elemental analysis, FT-IR, thermogravimetric analysis and photo-luminescence spectroscopy. Crystal data for 1: orthorhombic, Pca21 (No. 29), a = 12.5696(4) Å, b = 12.9506(6) Å, c = 25.2370(10) Å, Z = 4. The structure of 1 features one-dimensional (1-D) inorganic–organic hybrid zincoborate helical chain, which was constructed from the assembly of [B5O8(OH)2]3− clusters and Zn(dap) linkers. Adjacent zincoborate chains are further linked by [Zn(dap)3] complexes through extensive hydrogen-bonds to generate 3-D supramolecular network. Two distinct coordination-modes of zinc centers are simultaneously observed in the structure, and they play different roles in the formation of the resultant framework. In addition, 1 exhibits extensive luminescence and moderate second-harmonic generation efficiency.
