be mesogenic, it may be Cu(II) or UO(2)(VI) but not Ni(II), Zn(II), Co(II), or VO(IV). The crystalstructure of bis(5-hexadecyloxytropolonato)copper(II) shows how, even in the crystalline state, molecular packing is dominated by the interactions between alkyl chains, together with copper-oxygen interactions. In the Cu(II) complexes, strong interactions occur between Cu atoms and O atoms of neighboring
