Cyanobiphenyls, nCB and nOCB, have been widely studied and are key materials to reveal the relationship between crystal structures and mesophase behavior. Crystal structures of nCB (n≦5, n=9-11) and nOCB (n=1-10, 12) were reported. Now, nCB (n=6-8) with low melting points have been determined at low temperature. The crystal of 7CB has a smectic like layer structure, which is similar to those of 9CB and 11CB. Crystal of 8CB has an imbricated structure, which is similar to that of 10CB. Crystal of 6CB does not have either packing mode. Thus, the structures of nCB (n≧7) show an even-odd effect. Compared with the reported crystal structures of nCB (n≦4), an interaction between CN groups and between CN group and biphenyl group is shown for n=even and n=odd, respectively. This tendency is quite different from that of nOCB.
