The title compound, Pt(2)(C(16)H(11)N(2))(2)(C(18)H(17)N(2)P)(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)].
标题化合物Pt₂(C₁₆H₁₁N₂)₂(C₁₈H₁₇N₂P)₂包含两个Pt(II)原子，由N-[(二苯基膦基)甲基]吡啶-2-胺(dppmp)配体桥连。一个Pt原子由dppmp配体中的一个P原子以及6-苯基-2,2'-联吡啶(pbpy)配体中的一个C原子和两个N原子以平面正方形几何构型配位。另一个Pt原子由dppmp配体中的一个N原子以及另一个pbpy配体中的一个C原子和两个N原子以平面正方形几何构型配位。pbpy配体之间存在分子内π-π相互作用，两个吡啶环之间的质心-质心距离为3.62 (1) Å。两个高氯酸根阴离子的氧原子无序，各自处于两个不同位置[占有率分别为0.49 (3)/0.51 (3)和0.48 (2)/0.52 (2)]。
