8-Chloro-6-iodo-2-phenyl-chromeno[4,3-c]pyrazol-4(2H)-one N,N-dimethyl-formamide monosolvate
Abstract:
In the title compound, C(16)H(8)ClIN(2)O(2)·C(3)H(7)NO, the fused tricyclic pyrazolo-coumarin ring and the N-phenyl ring are almost coplanar, the dihedral angle between them being 1.86 (9)°. In the crystal, these rings stack on top of each other via π-π inter-actions [centroid-centroid distances = 3.489 (2), 3.637 (2), 3.505 (2) and 3.662 (2) Å], forming infinite chains along the a axis. The chains are connected into layers parallel to ac plane through I⋯O inter-actions [3.0011 (18) Å] between pairs of symmetry-related mol-ecules. The DMF solvent mol-ecules are C-H⋯O bonded to this network.
