The title copper(II) complex, [Cu(C22H18N6)(2)](ClO4)(2)center dot 2C(2)H(3)N, comprises two neutral substituted tris(pyrazol-1-yl) methane ligands bonded to a central Cu II ion, which is positioned on a crystallographic inversion center. Six Cu-N bonds are arranged in a distorted octahedral fashion. The unsubstituted pyrazole rings on each ligand are oriented trans with respect to each other, interdigitated with the two 3-phenylpyrazole rings of the other ligand.

In this paper we show that simple tris(pyrazolyl)methane (Tpm) ligands can be equilibrated with substituted pyrazoles to form new 'mixed' tris(pyrazolyl)methanes. The product ratio depends on the nature of the starting tris(pyrazolyl)methane, the nature of the substituted pyrazole, and the relative amounts of these two reagents. The method has been used to easily synthesize several new asymmetric and functionalized Tpm ligands. (C) 2000 Elsevier Science Ltd. All rights reserved.
