The crystal and molecular structure of NN′-bisuccinimidyl

Abstract

NN′-Bisuccinimidyl crystallises in the space group C2/c with a= 10·268, b= 9·218, c= 10·072 Å, β= 115·38°. Z= 4. The structure, determined by a three-dimensional X-ray analysis, shows the molecule to have a crystallographic two-fold symmetry axis parallel to the N–N bond, and non-crystallographic 222 symmetry. The ring planes make a dihedral angle of 65°. Mean bond lengths are N–N 1·37, N–C 1·39, CO 1·21, C(O)–C(H₂) 1·50, and C(H₂)–C(H₂) 1·52 Å.
