✦ Synopsis

Br 2 N + ÁBr À , lie in a crystallographic mirror plane. The packing within the plane is determined by hydrogen bonds N + ÐHÁ Á ÁBr À and CÐ HÁ Á ÁBr À , and by BrÁ Á ÁBr contacts, but differs from that of the previous polymorph [Freytag & Jones (2001). Z. Naturforsch. Teil B, 56, 889±869], which also lay completely in mirror planes.

A second monoclinic polymorph of 5,6-diphenyl-3-(2-pyridyl)-1,2,4-triazine, C 20 H 14 N 4 , is reported. The unit-cell dimensions and the orientation of the pyridine ring with respect to the triazine ring are different from those of the previously reported monoclinic form [Eltayeb, Teoh, Ng, Fun & I
