Three complexes, (PBT)W(CO)5 (1), (3,5-Me2PBT)W(CO)5 (2) and (3,5- Pr2PBT)W(CO)5 (3) (PBT = 1H-(pyrazol-l-ylmethyl)-l,2,3-benzotriazole), were synthesized, and two of them were structurally chara... Three complexes, (PBT)W(CO)5 (1), (3,5-Me2PBT)W(CO)5 (2) and (3,5- Pr2PBT)W(CO)5 (3) (PBT = 1H-(pyrazol-l-ylmethyl)-l,2,3-benzotriazole), were synthesized, and two of them were structurally characterized by X-ray crystallography. Complex 1 crystallizes in monoclinic with space group P21/c, α = 1.0828(2), b = 2.1655(4), c = 0.6982(1) nm, β = 93.39(3)°, V= 1.6343(6) nm3, Z = 4, Dc = 2.126 g/cms, F(000) = 992, β = 7.107 mm1, S = 0.990, the final R = 0.0301 and wR = 0.0685. Complex 2 crystallizes in triclinic with space group Pi, a = 0.95021(8), b = 0.98391(6), c - 1.1433(1) nm, α = 68.792(7), β = 77.860(8), γ= 75.533(6)°, V= 0.9563(1) nm3, Z = 2, Dc = 1.914 g/cm3, F(000) = 528, β = 6.078 mm-1, S = 1.042, the final R = 0.0253 and wR = 0.0549. 1H-(Pyrazol-l-ylmethyl)-l,2,3-benzotriazoles acted as monodentate ligands through the 3-position nitrogen of the triazolyl group, and the pyrazolyl nitrogen did not participate in coordinating to the metal centers in these complexes. Their UV and fluorescence properties have been studied. 展开更多
