摘要：

The trinuclear copper(I) cation, [Cu(mu-ppdBu)(2){Cu(cnge)(MeCN)}(2)](BF4)(3).MeCN (ppdBu = 3,6-bis[N{3-(tert-butyl)pyrazolyl}] pyridazine, cnge = 2-cyanoguanidine), which comprises three copper atoms held together in an isosceles triangle (Cu...Cu = 3.62, 3.63 and 5.01 Angstrom) by two approximately perpendicular (dihedral angle 86.9 degrees) planar ppdBu bridging ligands, is synthesised by addition of a dichloromethane solution of ppdBu to an acetonitrile solution of [Cu(MeCN)(4)](BF4) containing cnge.
