2-Chloro-benzene-1,4-diaminium bis-(dihydrogenphosphate).

ABSTRACT: The asymmetric unit of the title salt, C(6)H(9)ClN(2) (2+)·2H(2)PO(4) (-), contains two dihydrogenphosphate anions and one 2-chloro-benzene-1,4-diaminium dication. The H(2)PO(4) (-) anions are inter-connected through strong O-H?O hydrogen bonds to form two-dimensional infinite layers parallel to (001). The organic entities are anchored to the inorganic layers through N-H?O hydrogen bonds, and through weak C-Cl?O halogen bonds [3.159?(2)?Å, 140.48?(7)°]. No ?-? stacking inter-actions between neighboring aromatic rings or C-H?? inter-actions towards them are observed. Minor disorder is observed for the Cl atom and one hy-droxy group [minor-component occupancy = 3.29?(9)%].
