| Abstract |
Crystal structures of two bis-phenols namely bis-(3,5-dimethyl-2-hydroxyphenyl)(3-aminophenyl)methane 1 and bis-(3,5-dimethyl-4-hydroxyphenyl)(3-aminophenyl)methane 2 are determined. The compound 1 crystallises in monoclinic P2(1)/c with a = 12.2579(16) angstrom, b = 16.0906 ( 19) angstrom, c = 10.6664( 13) angstrom, beta = 115.417(7)degrees, V = 1900.2 ( 4) A 3 whereas 2 crystallizes in monoclinic C2/c, a = 9.2538( 2) angstrom, b = 18.6579( 4) angstrom, c = 23.2725( 5) angstrom, beta = 98.796( 2)degrees, V = 3970.89( 15) angstrom(3). The crystal lattice of both the compounds shows presence of N-H center dot center dot center dot pi interactions but no O-H center dot center dot center dot pi interactions. |
