Abstract
Yellow crystals of [Zn(N,N′-bis (5-bromosalicylidene) 2,3-diaminopyridine)] Pyridine, [Zn(C19H11Br2N3O2)]C5H5N, have been obtained and characterized by elemental analysis, FT-IR, UV–Vis, 1H NMR spectroscopy and MALDI-TOF mass spectrometry. The structure has been determined by single crystal X-ray crystallography. The complex crystallizes in the triclinic space group P-1 with two molecules in the asymmetric unit and with unit cell dimensions a = 8.0103(3) A, b = 12.8340(5) A, c = 22.3682(11) A, α = 91.715(2)°, β = 93.918(2)°, γ = 103.708(2)°. V = 2226.30(16) A3, Z = 4, R 1 = 0.0780 and wR 2 = 0.1192. X-ray structure determination revealed that the complex consists of a [Zn(C19H11Br2N3O2)] moiety with a coordinated pyridine molecule on the metallic centre. The zinc atom adopts a distorted square pyramidal geometry as it is shown in the crystal structure.
