Columnar Formation in Sodium Triphenylacetate
Artikel i vetenskaplig tidskrift, 2014

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) angstrom, b = 13.5992(3) angstrom, c = 15.5288(3) angstrom, a = 76.7270(11)degrees, b = 74.4500(11)degrees, c = 84.7410(13)degrees, M-W = 656.65, V = 1659.42(6) angstrom(3), 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.
