A new metal complex compound with the composition [Co(2-hnaph)2(1,2-phen)2]∙Cl-∙C2H5OH was synthesized by the interaction of 2-hnaph (2-hydroxy-1-naphthaldehyde), 1,2-phen (1,2-phenylenediamine), and CoCl2∙6H2O in ethyl alcohol solutions. The composition, molecular and crystal structures of this metal complex compound were investigated using differential scanning calorimetry (DSC), IR spectroscopy, and X-ray diffraction analysis (XRD). DSC analysis revealed that the thermal decomposition of the organic component in the complex varies, beginning at 75°C and ending in the temperature range of 370°C. A reaction occurs between the oxygen of the carbonyl group in the aldehyde form of 2-hnaph and the amino (NH2) groups of 1,2-phen, resulting in the release of one water molecule (>C=O + -NH2 → >C=N- + H2O). Analysis of two-dimensional fingerprint region plots revealed that H...O/O...H, H...H, and H...C/C...H interactions make the greatest contribution to the Hirshfeld surface. In the complex compound, H...H interactions account for 47.2%, H...C/C...H for 34.4%, and H...Cl/Cl...H for 9.2%, which is the expected state for molecules dominated by oxygen atoms. The complex compound contains H...H (47.2%), H...C/C...H (34.4%), and H...Cl/Cl...H (9.2%), which is the expected state for molecules dominated by oxygen atoms.
