Abstract

4-4'-Cyanophenoxy-carbonyl-phenyl-4-(trimethylsilyl) ethynyl]benzoate a rod shaped liquid crystal (SmA) is synthesized and characterized. The single-crystals were grown in triclinic crystal system in the space group of Pi with unit cell parameters a = 5.9577(2) angstrom, b = 8.0398(3) angstrom, c = 25.8842(9) angstrom, alpha = 86.096(2)degrees, beta = 89.912(2)degrees, gamma = 2.919(2)degrees, Z = 2 , and V = 1182.16(7). The crystal structure is stabilized by C-H center dot center dot center dot O intra-molecular interactions. Further ,the structure also involves C-H center dot center dot center dot pi interactions and weak pi-pi stacking interactions centroid-centroid separation = 3.806 (3) angstrom].
