Synthesis, Structure and Hirshfeld Surface Analysis of the Metal Complex Formed by Cluster-Type 2-Hydroxy-1-Naphthaldehyde with Zn2+ Ion

A new metal complex compound [Zn2(2-hnaf)2(NO3)2 (H2O)2] was synthesized by the reaction between solutions of 2-hydroxy-1-naphthaldehyde (2-hnaf) and Zn(NO3)23H2O in ethyl alcohol.The composition, molecular and crystal structures of this metal complex compound were investigated using X-ray structural analysis (XRD).The data obtained from XRD analysis also confirmed the presence of coordinated water molecules.2-hnaf is bound to the central atom via oxygen atoms.Bond lengths OA1-ZnA1, OA2-ZnA1 and OA2-ZnB1 (as well as bond lengths OB1-ZnB1, OB2-ZnB1 and OB2-ZnA1) are 2.051, 2.012 and 2.073 , respectively.In the complex compound, the nitrate anion is also bidentately bonded to the central atom, with each ligand having two rings, forming a chelate with a total of four membered rings.Based on the obtained data, the Hirshfeld surface analysis of the complex was studied.The results of the surface analysis revealed that the majority of interactions are H...O/O...H (35.8%),H...H (24.3%),H...C/C...H (23.
