title: Bis(2-amino-pyridinium) 2,5-dicarb-oxy-benzene-1,4-dicarboxyl-ate.
abstract: In the title compound, 2C(5)H(7)N(2) (+)·C(10)H(4)O(8) (2-), the 2-amino-pyridinium (2-apyH) cation and 2,5-dicarb-oxy-benzene-1,4-dicarboxyl-ate (btcH2) anion are both nearly planar, with r.m.s. deviations of 0.015 and 0.050 Å, respectively. The angle between the latter least-squares planes is 17.68 (9)°. The overall crystal structure results from the packing of two-dimensional networks, formed by alternating 2-apyH and btcH2 linked by hydrogen bonds, parallel to (100).
