title: Bis(triphenyl-guanidinium) tetra-chlorido-cuprate(II).
abstract: The structure of the title compound, (C(19)H(18)N(3))(2)[CuCl(4)], consists of square-planar [CuCl(4)](2-) anions and triphenyl-guanidinium cations. The Cu(II) ion occupies a crystallographic inversion centre. In the cation, the dihedral angles between the phenyl rings and the plane defined by the central guanidinium fragment are in the range 51.9 (4)-64.4 (3)°. N-H⋯Cl hydrogen bonds assemble the ions into infinite chains running along the b axis.
