A new sodium salt, sodium triphenylacetate has been synthesized and characterized by single-crystal X-ray diffraction: triclinic, P-1 with a = 8.3846(2) Å, b = 13.5992(3) Å, c = 15.5288(3) Å, α = 76.7270(11)°, β = 74.4500(11)°, γ = 84.7410(13)°, M W = 656.65, V = 1659.42(6) Å3, Z = 2. The triphenylacetic molecules bridge the metallic ions forming an infinite columnar structure. Calorimetric data does not support the existence of a mesophase induced by temperature.
