Main Group Pyrazolates - the X-Ray Structures of [Al(η2-But2pz)3], [SnMe3(η1-Ph2pz)] and [GePh3(η1-But2pz)] (R2pz = 3,5-Disubstituted Pyrazolate)

From metathesis reactions between AlCl3, SnMe3Cl, or GePh3Br and the appropriate potassium 3,5-disubstituted pyrazolate [K(R2pz)] the complexes [Al(But2pz)3], [SnMe3(Ph2pz)], [SnMe3(But2pz)], and [GePh3(But2pz)] have been obtained. The X-ray structure of [Al(But2pz)3] shows the complex to be monomeric with η2-pyrazolate groups, in a quasi-trigonal prismatic array: the first monomeric homoleptic tris(pyrazolato) complex of any element. X-Ray structures of [SnMe3(Ph2pz)] and [GePh3(But2pz)] reveal mononuclear species with distorted tetrahedral stereochemistries and η1-pyrazolate groups. Comparisons of spectroscopic data between [SnMe3(Ph2pz)] and [SnMe3(But2pz)] suggest the latter is also four-coordinate with an η1-But2pz ligand.
