Crystal Structure of Nitrato(2,2',2'-terpyridyl)platinum(II)Hydrogen Dinitrate,[Pt(terpy)ONO_2] [H(ONO_2)_2]

摘要

The title compound,C_(15)H_(12)N_6O_9Pt,consists of [Pt(terpy)ONO_2]~+ cation and [H(ONO_2)_2]~-anion,in which 2 nitrate groups are linked by a strong hydrogen bond [O…O 2449(1)A].In the cation,the terpyridine is coordinated to Pt as a tridentate ligand and the fourth position is occupied by the nitrate ion's oxygen.The coordination around Pt is square-planar.The coordinated nitrate moiety adopts a distorted trigonal-planar configuration.It belongs to the space group P1 with a=8.605(2),b=10.220(3)A,c=10.517(2)A and alpha=89.51(1),beta=82.78(2),gamma=76.90(2)deg .
