    In this contribution, a series of copper(ii) discrete and polymeric coordination compounds, namely [Cu3L2(aze)2]nnH2O (1nH2O), [CuL2]H2O (2H2O) and [CuL(H2O)(Haze)]H2O (3H2O) were fabricated from (pyridin-2-yl)methylenenicotinohydrazide (HL) and azelaic acid (H2aze), using evaporative crystallization, grinding and slurry synthesis methods. The solvent crystallization method produced a crystalline precipitate of complex 1nH2O. The filtrate allowed the production of crystals of complex 3H2O. The grinding synthetic method gave rise to a mixture of complexes 1nH2O, 2H2O and an undetermined phase. Results of the slurry synthetic approach highly depend on the stirring time. The obtained coordination compounds have been fully characterized by single crystal X-ray diffraction revealing different structures of complexes, viz. from mononuclear homo- and heteroleptic complexes (2 and 3) to a 1D heteroleptic coordination polymer (1). DFT calculations on non-polymeric complexes were conducted to evaluate the hydrogen-bonding and pi-stacking interactions that play a critical role in the solid-state structures of complexes 2 and 3. Additionally, the impact of co-crystallized water molecules, which enhance the pi-stacking interactions, was analyzed using energy decomposition analysis.
