摘要：
The structure of the symmetrical Schiff base, N,N'-[bis(pyridin-2-yl)formylidene]ethane-1,2-diamine (bpfd) has been characterized by single crystal X-ray diffraction. The non-covalent supramolecular chemistry involved in the crystal structure of this ligand has been carefully investigated. The structure adopted different motifs of nitrogen-hydrogen interactions that led to the formation of centrosymmetric dimers. In addition, edge-edge and face-face nitrogen-nitrogen interactions were observed and reported. The Schiff base (bpfd) ligand crystallizes in a monoclinic space group C12/cl with a = 19.128(2) angstrom; b = 5.8776(6) angstrom; c = 13.1403(15) angstrom; alpha = 90 degrees; beta = 121.970 degrees (4); gamma = 90 degrees and z = 4. This structure is an example of compounds with many symmetry-independent molecules in the asymmetric unit cell (Z > 2).
