title: A double mesogen based on linked p-terphenyl units.
abstract: The structure of bis(4,4"-decyloxy-p-terphenyl-2'-ylmethyl) carbonate, C(79)H(110)O(7), (I), has been determined at 123 K. It is a new type of twin mesogen. No two adjacent aromatic rings are coplanar and the four decyloxy side chains are maximally extended. Molecules of the compound are packed along the crystallographic a axis. The molecular arrangement is a precursor of a smectic A phase.
