Three complexes, (PBT)W(CO)5 (1), (3,5-Me2PBT)W(CO)5 (2) and (3,5- Pri2PBT)W(CO)5 (3) (PBT = 1H-(pyrazol-1-ylmethyl)-1,2,3-benzotriazole), were synthesized, and two of them were structurally characterized by X-ray crystallography. Complex 1 crystallizes in monoclinic with space group P21/c, a = 1.0828(2), b = 2.1655(4), c = 0.6982(1) nm, β = 93.39(3)º, V = 1.6343(6) nm3, Z = 4, Dc = 2.126 g/cm3, F(000) = 992, μ = 7.107 mm-1, S = 0.990, the final R = 0.0301 and wR = 0.0685. Complex 2 crystallizes in triclinic with space group P, a = 0.95021(8), b = 0.98391(6), c = 1.1433(1) nm, = 68.792(7), β = 77.860(8), = 75.533(6)º, V = 0.9563(1) nm3, Z = 2, Dc = 1.914 g/cm3, F(000) = 528, μ = 6.078 mm-1, S = 1.042, the final R = 0.0253 and wR = 0.0549. 1H-(Pyrazol-1-ylmethyl)-1,2,3-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.
