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.
在标题化合物C(16)H(8)ClIN(2)O(2)·C(3)H(7)NO中,稠合的三环吡唑并香豆素环和N-苯基环几乎共面,它们之间的二面角为1.86 (9)°。在晶体中,这些环通过π-π相互作用[质心-质心距离 = 3.489 (2)、3.637 (2)、3.505 (2)和3.662 (2) Å]相互堆叠,沿a轴形成无限链。这些链通过对称相关分子对之间的I⋯O相互作用[3.0011 (18) Å]连接成平行于ac平面的层。DMF溶剂分子通过C-H⋯O键合到该网络。
