3,4,5-Trihy-droxy-benzohydrazidium perchlorate-3,4,5-trihy-droxy-benzohydrazide-water (1/1/1).

ABSTRACT: The crystal studied of the title compound, C(7)H(9)N(2)O(4) (+)·ClO(4) (-)·C(7)H(8)N(2)O(4)·H(2)O, was found to be a racemic twin with a 0.72?(18):0.28?(18) domain ratio. The hydrazidium group is close to planar, with an r.m.s deviation of 0.105?Å; the hydrazide group deviates more from planarity, with an r.m.s deviation of 0.174?Å. In the crystal, the hydrazidium cation, hydrazide mol-ecule, perchlorate anions and water mol-ecules are linked through O-H?O, N-H?O and C-H?O hydrogen bonds into a three-dimensional supra-molecular network. In addition, the benzene rings of the hydrazidium and hydrazide units are connected via ?-? inter-actions into infinite chains along the c axis; the centroid-centroid distances are 3.486?(3) and 3.559?(3)?Å.
