✦ Synopsis

The title compound 1a crystallized with a molecule of chloroform in a triclinic lattice, space group P-1, with a=16.5215(19) A ˚, b=17.4181(19) A ˚, c=18.7403(18) A ˚, a=78.328(8) , b=64.210(8) , =87.863(9) , Z=2. The molecule assumes a not yet observed conformation with approximate (not crystallographic) C 4V -symmetry with the inclusion of one molecule of chloroform in the molecular cavity. Layers of molecules are packed in alternating order in the crystal lattice.
