Cytochrome-c3 has two quite different heme- heme interaction models, "gable"-type and "twist"-type.Bis m-(meso-triphenylporphinyl) benzene was newly prepared as a gable conformation model.This "gable" porphyrin exhibited moderate porphyrin-porphyrin and heme-heme interaction.

3-(α,α′-Dibromomethyl)benzyl 1-4 benzotriazole, C 14H11Br2N3, F.W,= 381.08, tridinic, P1, a= 8.411(1)A, b=9.008(1)A, c=9.714(1) A, α=97.74(1)°, β=103.11(1)°, ;γ=101.62(1)°, V=689.4(1)A3, Z=2, Dcal=1.836Mgm-3, μ-7.364mm-1, λ(CuKα)=1.5418A, final R1 and wR2 are 0.0538 and 0.1383, respectively. The title compound is a precursor for the macroligand stilbenobenzo-triazolophane. Unusual short bond length in the benzotriazole ring suggests the delocalization effect on the bonding. Intermolecular C-H...π, C-H... Br, and some face-to-face π-π interactions play a role in stabilizing the delocalized form. The molecules in the unit cell are stabilized by C-H... N type of interactions in addition to van der Waals forces.
