(H2pdcCuBr2)2∙2(MH+)∙2Br (M = Melamine, H2pdc = Pyridine-2,6-Dicarboxylic Acid): Crystal Structure, Hirshfeld Surface Analysis, Vibrational and Thermal Studies



This paper describes the synthesis, as well the structural of a novel complex of Cu(II) with pyridine-2,6-dicarboxylic acid and melamine. The complex was characterized by differential scanning calorimetry (DSC) analysis, Fourier transform infrared and Raman spectroscopy with a detailed analysis of Hirshfeld surfaces and fingerprint plots. The single X-ray diffraction studies have revealed that the compound crystallizes in triclinic P\(\bar{1}\) space group with cell parameters a = 6.9839 (14), b = 11.037 (2), c = 12.990 (2), α = 72.268 (9), β = 75.237 (9), δ = 87.855 (10) and Z = 1. The crystal structure was stabilized by an extensive network of N–H···Br, N–H···O, O–H···N, O–H···Br, C–H···Br and non-classical N–H···N hydrogen bonds. Furthermore, the room temperature IR and Raman spectra of the title compound were recorded and analyzed on the basis of literature data. The DSC study shows three anomalies at 385, 495 and 507 K.
