Abstract
The title compound, $C_15H_12N_6O_9Pt$, 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)$AA$]. 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 $Pbar{1}$ with a = 8.605(2), b = 10.220(3) $AA$, c = 10.517(2) $AA$ and $alpha$ = 89.51(1), $beta$ = 82.78(2), $gamma$= $76.90(2)^circ$.
