%X From metathesis reactions between AlCl3, SnMe3Cl, or GePh3Br and the appropriate potassium 3,5-disubstituted pyrazolate &#91;K(R2pz)&#93; the complexes &#91;Al(Bu t 2pz)3&#93;, &#91;SnMe3(Ph2pz)&#93;, &#91;SnMe3(Bu t 2pz)&#93;, and &#91;GePh3(Bu t 2pz)&#93; have been obtained. The X-ray structure of &#91;Al(Bu t 2pz)3&#93; shows the complex to be monomeric with &#951;2 -pyrazolate groups, in a quasi-trigonal prismatic array: the first monomeric homoleptic tris(pyrazolato) complex of any element. X-Ray structures of &#91;SnMe3(Ph2pz)&#93; and &#91;GePh3(Bu t 2pz)&#93; reveal mononuclear species with distorted tetrahedral stereochemistries and &#951;1 -pyrazolate groups. Comparisons of spectroscopic data between &#91;SnMe3(Ph2pz)&#93; and &#91;SnMe3(Bu t 2pz)&#93; suggest the latter is also four-coordinate with an &#951;1 -Bu t 2pz ligand.
