Crystal Structure of N,N-Disalicylidene

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) Å 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 (I)). The N,N-disalicylidene-(R,S)(S,R)1, 2-ethanediamine molecules exhibit intramolecular N-H-O and are connected by C-H. . .O and C-H. . .interactions to form a 2D supramolecular network.
