Bis(piperazinediium) benzene-1,2,4,5-tetra-carboxyl-ate hexa-hydrate.

ABSTRACT: 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-tetra-carboxylic 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?? inter-actions, 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.

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-tetra-carboxylic 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 inter-actions, 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. ...[more]
