✦ Synopsis
cis isomers of 2-catecholboryl-1-pinacolboryl-and bis(1,2pinacolboryl)-1,2-bis[4-(trifluoromethyl)phenyl]ethene substitute one another isomorphously in a 1:1 ratio. The molecule has no crystallographic symmetry, with one olefinic site shared equally between superimposed pinacol-and catecholboryls, and the other occupied solely by a (disordered) pinacolboryl. CF 3 groups and hexane solvent molecules are also disordered.

The title compound, C~26~H~36~N~2~O~6~P~2~, possesses a crystallographically imposed inversion centre. The molecules are linked into a one-dimensional structure along the __c__ axis by a centrosymmetric system of weak C—H...O hydrogen bonds.
The title compound, C 20 H 14 N 12 S 2 , was synthesized by the reaction of 3-hydrazino-1H-1,2,4-triazole with phenyl isocyanate in benzene and by ring closure in an alkaline medium. Intermolecular N-HÁ Á ÁN hydrogen bonds are observed and these form a five-membered ring.
