The title compound, [Pt(2)(C(16)H(11)N(2))(2)(C(18)H(17)N(2)P)](ClO(4))(2), contains two Pt(II) atoms, bridged by an N-[(diphenyl-phosphino)meth-yl]pyridin-2-amine (dppmp) ligand. One Pt atom is coordinated by one P atom from the dppmp ligand, and one C atom and two N atoms from a 6-phenyl-2,2'-bipyridine (pbpy) ligand in a square-planar geometry. The other Pt atom is coordinated by one N atom from the dppmp ligand, and one C atom and two N atoms from another pbpy ligand in a square-planar geometry. There are intra-molecular π-π inter-actions between the pbpy ligands, with a centroid-centroid distance of 3.62 (1) Å between two pyridyl rings. The oxygen atoms of both perchlorate anions are disordered, each over two different positions [occupanicies 0.49 (3)/0.51 (3) and 0.48 (2)/0.52 (2)].
