Crystal structure of N,N-disalicylidene-(R,S)(S,R)-1,2-ethanediamine

Abstract

N,N-disalicylidene-(R, S)(S, R)-1,2-ethanediamine crystallizes in orthorhombic space group Pbca with a = 9.5634( 6), b = 14.2917( 9), c = 16.9181( 8) angstrom and Z = 4. The crystal structure was solved by direct methods and refined by full-matrix least squares to final values R1 = 0.0 + 399 and wR2 = 0.1004 with 2755 reflections ( I > 2 sigma(I)). The N,N-disalicylidene-(R, S)(S, R)-1,2- ethanediamine molecules exhibit intramolecular N-H center dot center dot center dot O and are connected by C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions to form a 2D supramolecular network.
