2,2'-(1,3,5,7-Tetra-oxo-1,2,3,5,6,7-hexa-hydro-pyrrolo[3,4-f]isoindole-2,6-di-yl)diacetic acid N,N-dimethyl-formamide disolvate.


ABSTRACT: The asymmetric unit of the title compound, C(14)H(8)N(2)O(8)·2C(3)H(7)NO or L·2DMF (DMF = N,N-dimethyl-formamide), contains one half of the centrosymmetric mol-ecule L and one solvent mol-ecule, which is disordered between two orientations in a 0.555?(4):0.445?(4) ratio. Inter-molecular O-H?O hydrogen bonds link one L and two DMF mol-ecules into a centrosymmetric hydrogen-bonded cluster. The crystal packing is further stabilized by weak inter-molecular C-H?O hydrogen bonds.

The asymmetric unit of the title compound, C(14)H(8)N(2)O(8)·2C(3)H(7)NO or L·2DMF (DMF = N,N-dimethyl-formamide), contains one half of the centrosymmetric mol-ecule L and one solvent mol-ecule, which is disordered between two orientations in a 0.555 (4):0.445 (4) ratio. Inter-molecular O-H⋯O hydrogen bonds link one L and two DMF mol-ecules into a centrosymmetric hydrogen-bonded cluster.
