Bis(piperazinediium) benzene-1,2,4,5-tetra­carboxyl­ate hexa­hydrate

The title compound, 2C(4)H(12)N(2) (2+)·C(10)H(2)O(8) (4−)·6H(2)O or (pipzH(2))(2)(btc)·6H(2)O, was formed from the reaction between benzene-1,2,4,5-tetra­carboxylic acid (btcH(4)) as a proton donor and piperazine (pipz) as a proton acceptor. A variety of O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds, as we...

Sumario:The title compound, 2C(4)H(12)N(2) (2+)·C(10)H(2)O(8) (4−)·6H(2)O or (pipzH(2))(2)(btc)·6H(2)O, was formed from the reaction between benzene-1,2,4,5-tetra­carboxylic acid (btcH(4)) as a proton donor and piperazine (pipz) as a proton acceptor. A variety of O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds, as well as C—H⋯π inter­actions, are present in the crystal structure. Two water O atoms are each disordered over two positions; for both the site occupany factors are ca 0.66 and 0.34.
