The connection of square-planar [Ni(CN)4]2− ions with Ph3Sn+ ions results in 1, a noninterpenetrated three-dimensional coordination polymer with an expanded NbO structure. The (Ph3Sn)2Ni(CN)4 framework (shown schematically without phenyl groups and solvent molecules) displays a large central cavity that is occupied by Ph3SnOH, acetonitrile, and water molecules.
