Abstract
Crystal structures determined for eight compounds R-C6H4-C6H4-COO-C6H4-R ', where R and R ' are achiral, four with octyloxy and/or octyl chains and four with a methyl or methoxy group at one end, are classified into three modes. First is a smectic-like layer composed of parallel molecules with closely arranged ester linkages; second is a layer comprising two crystallographically independent molecules, among which the ester linkages are close. Compounds with an octyloxy chain take these modes. Thirdly, for molecules with alkyl chains, the ester linkages are far apart among the parallel molecules. Melting and clearing points suggest stronger intermolecular interactions in the former two modes than in the last mode.
