The title compound, [NiCl2(C6H8N2)(2)], contains centrosymmetric molecules
with two phenylenediamine ligands coordinated in a bidentate fashion. The N
i-N distances are 2.088 (1) and 2.096 (1) Angstrom, and the Ni-Cl distance
of 2.4635 (4) Angstrom. The plane of each phenylenediamine molecule makes a
dihedral angle of 26.53 (7)degrees with the NiN4 plane. Extensive hydrogen
bonding leads to distinct cleavage in the bc plane.
