Descripción
Sumario:The formula unit of the title compound, 2C(6)H(7)N(2)O(+)·C(2)O(4) (2−), comprises two symmetry-equivalent 4-(hydroxy­imino­meth­yl)­pyridinium cations on general positions, linked through hydrogen bonding via an oxalate anion that resides on a crystallographic centre of symmetry. The crystal structure consists of infinite chains of cations and oxalate anions directed by O—H⋯O and multicentre N—H⋯O inter­molecular hydrogen-bonding inter­actions.
