The Structure of Tris(3',5'-dimethylpyrazol-1-yl)-s-triazine and Its Use as a Ligand in Coordination Chemistry

The crystal and molecular structure of the title compound (Me2-TPzT) has been determined by X-ray analysis. The observed molecular conformation presents the nitrogen atoms of three pyrazole rings in the same relative positions. The molecules are joined through intermolecular contacts forming chains that are arranged in a distorted hexagonal symmetry. Two complexes containing this ligand have been prepared: [{Pd(en)}3(Me2-TPzT)](PF6)6 and [{Ag(PPh3)}3(Me2-TPzT)](ClO4)3, which, due to their insolubility, have been characterized only by microanalysis, IR, 1H NMR and, in the latter case, by mass spectrometry.
