Crystalline polyoxo-titanium clusters(PTCs),as a molecular model of TiO_(2)nanomaterials,have attracted unprecedented attention due to their designable structure,tunable band gap,catalysis,and photochromic properties.A new trinuclear Ti3-oxo cluster,[Ti3(μ2-O)(μ3-O)(abz)_(6)(OiPr)_(2)]·CH_(3)CN·H_(2)O(Ti3),was synthesized by solvothermal method with a yield of 60%by using 4-aminobenzoic acid as ***-crystal X-ray diffraction shows that it has a[Ti3(μ2-O)(μ3-O)(abz)_(6)(OiPr)_(2)]trinuclear cluster ***3 crystallizes in monoclinic space group P21/c with a=11.091(1),b=22.837(2),c=22.754(1)Å,β=90.580(6)°,V=5763.0(6)Å3,Z=4,Dc=1.345 g·cm-3,F(000)=2412,μ=2.743 mm^(−1),R=0.0796,and wR=0.2260(I>2σ(I)).Ti3 shows typical semiconductive behavior determined by temperature-dependent conductivity *** chemiresistive humidity sensor fabricated by Ti3 showed good performance,including high response(four orders of magnitude current change from 0 to 100%RH)and fast response time(160 s)and recovery time(26 s).
