Abstract:
In the title compound, [Pd(2)Cl(4)(C(8)H(6)N(4))]·C(3)H(7)NO, the two Pd(2+) 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 Pd(2+) cations. The dinuclear complex and the dimethylformamide solvate molecule lie on the inter-section of a twofold rotation axis and a mirror plane, with disorder present in the solvate mol-ecule. 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 mol-ecule are disordered over two sets of sites of equal occupancy.
