Abstract : mu-(Pyrazolyl-N:N')-bis(2,2,'2 -terpyridine)platinum(II)) perchlorate acetonitrile solvate, Pt2(Cl5HllN3)2(C3H3N2)(ClO4)3.CH3CN, M(sub r) = 1263.18, orthorhombic, Pnma a = 18.172 (2), b = 17.950 (3), c = 12.086 (4) A, V = 3942.3 (15) A(3), Z = 4, D (sub x) = 2.128 g /cu cm, lambda(Mo K(alpha) = 0.71073 A, mu = 74.41 /cm, F (000) = 2416, room temperature (297K), R = 0.0337 for 2510 reflections with F(2) sub omicron 3 sigma (F(2) sub omicron). A single pyrazolyl unit bridges two Pt centres. The square-planar coordination around each Pt atom is completed by a tridentate terpyridine ligand. The Pt...Pt separation is 3.432 (1) A with an inclination of 47.7 (12) deg between the two Pt square planes.
