title: Suppression of the Jahn-Teller distortion in a six-coordinate copper(II) complex by doping it into a host lattice.
abstract: The electronic structures of [Cu(terpy)(2)](2+) and [Cu(bpp)(2)](2+) (bpp = 2,6-di[pyrazol-1-yl]pyridine) are different, when doped into [M(bpp)(2)][BF(4)](2) (M(2+) = Fe(2+) or Zn(2+)). The [Cu(terpy)(2)](2+) dopant is a typical pseudo-Jahn-Teller elongated copper(II) center. However, the [Cu(bpp)(2)](2+) sites show EPR spectra consistent with a tetragonally compressed {d(z(2))}(1) configuration.
