Abstract
In molecules of [Cu(TPPZ)Cl-2] [TPPZ is 2,3,5,6-tetra(2- pyridyl)pyraz ine], the central Cu-II atom has a square-pyramidal coordination envir onment, defined by three TPPZ N atoms and by two chloro ligands, one o f which is apical. The other three TPPZ N atoms remain uncoordinated. The Cu-N distances are in the range 1.975 (2)-2.058 (2) Angstrom and t he Cu-Cl bond lengths are 2.214 (1) and 2.465 (1) Angstrom.
