A Porous Organic-inorganic Hybrid Compound Constructed from Polyoxovanadium Borate Anions,Dinuclear Na Sites and Metal-organic Units

A polyoxovanadium borate [Na(H2O)]2[Na(H2O)2]2[Cu(en)2][V12B18O54(OH)6]·(H3O)2·(H2O)18 1(en = ethylenediamine) has been hydrothermally synthesized and characterized by IR,two-dimensional infrared(2D IR) correlation spectroscopy with magnetic and thermal perturba-tion,thermal IR spectroscopy,thermal gravimetric analysis and single-crystal X-ray diffraction.It crystallizes in triclinic,space group P1 with a = 12.981(3),b = 13.044(3),c = 14.208(3) ,α = 63.98(3),β = 77.17(3),γ = 14.208(3)°,V = 2001.0(8) 3,Z = 1,Mr = 2518.05,Dc = 2.090 g/cm-1,F(000) = 1255.0,Mu(mm-1) = 1.756,λ(MoKα) = 0.71073 ,R = 0.0625 and wR = 0.1952.In 1,the [V12B18O54(OH)6]8-units are connected by [Cu(en)2]2+,binuclear Na(1) and Na(2) to form a three-dimensional porous framework.     

Crystal Structure and Property Research on Compounds Co（Ⅱ） and Zn（Ⅱ） with 3-Methylbenzoic Acid

Two compounds with 3-methylbenzoic acid(HL) [Co(L)2(4,4'-bipy)]n 1 and [Zn2(L)4(4,4'-bipy)]n 2(L = 3-methylbenzoic acid) have been hydrothermally synthesized directly and characterized by single-crystal X-ray diffraction analysis,elemental analyses,IR spectra and ultraviolet-visible diffuse reflection integral spectra(UV-Vis DRIS).The two compounds are both one-dimensional infinite chains.The structural difference is that 1 is a double-chain structure and 2 is only a single chain one.At the same time,the carboxylate groups adopt different modes in the two compounds,relatively.Additionally,in order to explore the structural characteristic,two-dimen-sional IR spectra are investigated for 1 and 2.Photo-luminescent property of 2 is also researched in detail.
