✦ Synopsis
The asymmetric unit of the title compound, (C 11 H 9 N) 2 -[Sn(NO 3 ) 4 ], consists of a mononuclear complex anion and two non-coordinated 4-phenylpyridinium cations. The Sn IV atom, lying on a twofold rotation axis, is coordinated by eight O atoms of four NO 3 À anions. This mononuclear complex is further extended into a supramolecular network structure via non-classical hydrogen bonds between CH groups of cations and O atoms of neighbouring anions.
