title: Structure of trans-3,3-dichloro-4-(alpha-chlorobenzyl)-1-methyl-5-phenyl-2-pyrrolidi none.
abstract: C18H16Cl3NO, Mr = 368.69, triclinic, P1-, a = 10.360 (1), b = 10.397 (1), c = 10.810 (2) A, alpha = 60.84 (1), beta = 57.22 (1), gamma = 70.97 (1) degrees, V = 852 (1) A3, Z = 2, Dx = 1.437 Mg m-3, Mo K alpha radiation, lambda = 0.71073 A, mu = 0.54 mm-1, F(000) = 380, T = 293 (1) K, R = 0.0287 for 2330 observed reflections with I greater than 3 sigma (I). The five-membered ring has an envelope conformation and the 4-(alpha-chlorobenzyl) and 5-phenyl groups are trans with respect to each other.
