Figure 2 The crystal packing of the title compound, viewed along c-axis, showing bifurcated bonding including Cl2: C10-H10A...Cl2i hydrogen bonds and C25i-Cl2i...O2 halogen bonds, resulting into supramolecular chains [C_{2}^{1}][[R_{2}^{1}](6)] running parallel to [0 1 0] direction. The hydrogen atoms not involved in the hydrogen bonding have been excluded for clarity. The symmetry code: (i). [{3\over 2}] - x,-[{1\over 2}] + y,1/2 - z.  [article HTML]
