Differential thermal analysis (DTA), differential scanning calorimetry (DSC), polythermal polarized-light microscopy (PPM), and small-angle X-ray scattering are used to study the phase behavior of transition-metal decanoates (C9H19COO)2M, where M = Mn, Co, Ni, Cu, Zn, or Cd. All the salts, except zinc decanoate, have liquid-crystal properties. Manganese, cobalt, nickel, and copper decanoates form enantiotropic smectics A. Cadmium decanoate forms monotropic smectic A. The layers formed by organic anions in the mesophase are contracted. The higher the polarizing ability of the transition-metal cation, the stronger the contraction.
