Abstract

In the title compound, [Pd2Cl4(C8H6N4)]·C3H7NO, the two Pd2+ cations have a distorted square-planar coordination sphere and are bridged by a bis-bidentate 2,2′-bipyrimidine ligand. Two terminal chloride anions are also bonded to each of the Pd2+ cations. The dinuclear complex and the dimethylformamide solvate molecule lie on the intersection of a twofold rotation axis and a mirror plane, with disorder present in the solvate molecule. There is a slight distortion from the square-planar metal geometry, as indicated by the bite angles of 81.77 (13)° and 91.63 (5)°. The C and O atoms of the solvent molecule are disordered over two sets of sites of equal occupancy.
