| Abstract: Reaction of tungsten or molybdenum carbonyl with 3(5)-hydroxymethyl-5(3)-methylpyrazole (L1), 4-hydroxymethylpyrazole (L2) and bis(3-hydroxymethyl-5-methylpyrazol-1-yl)methane (L3) yielded complexes LW(CO)5 (L=L1 or L2) and L3M(CO)4 (M=Mo or W), respectively. These complexes have been fully characterized by NMR, IR and X-ray crystal structural analyses, indicating that they form 1D or 2D organometallic supramolecular architectures through O-H…O, N-H…O and O-H…OC-M hydrogen bonding interactions, and these structures are significantly affected by the relative position of the hydroxymethyl group on the pyrazole ring. In addition, these complexes show moderate catalytic activity for the cyclotrimerization reaction of phenylacetylene. |
