Summary The reactions of some copper(II) salts with bis(1-pyrazolyl)methane, H2Cbpz, bis(3,5-dimethylpyrazolyl)methane, H2Cbdmpz, and tris(1-pyrazolyl)methane, HCtpz give the following solid complexes: CuLX2 · nH2O (L=H2Cbpz, H2Cbdmpz or HCtpz; X=Cl−, Br−, NO 3 − , OAc−, or 1/2 SO 4 2− and n=0, 1, 3 or 5) and CuL2X2 · nH2O (L=HCtpz, X= C−, Br−, NO 3 − or ClO 4 − and n=0 or 2). The complexes have been characterised by elemental analysis, visible and i.r. spectral measurements. The reactions of Cu(HCtpz)X2 · nH2O (X=Cl− or Br−) with acetylacetonate (acac−), dialkyldithiocarbamate (S2CNMe 2 − , S2CNEt 2 − ) or poly(1-pyrazolyl)borate (H2Bbpz−, HBtpz−) in aqueous solutions lead to the displacement of HCtpz and the subsequent formation of neutral [Cu(acac)2], [Cu(S2CNR2)2], [Cu(H2Bbpz)2] and Cu(HBtpz)2 while the reaction with oxalate ion, C2O 4 2− yields a stable neutral solid compound, [Cu(HCtpz)(C2O4)].
