Sažetak

In this work, we have focused on the synthesis of a copper(II) complex with an imine derived from 4-nitroaniline (4noa) and 2-hydroxy-1-naphthaldehyde (n), as well as its coordinatively saturated adducts. The obtained metal complex is reasonably soluble in pyridine (py) and tetrahydrofuran (thf), resulting in the formation of two adducts. The complex and adducts have been synthesized both by conventional solvent-based methods and by liquid-assisted grinding (LAG). All products were characterized by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC) and powder X-ray diffraction (PXRD). Their crystal and molecular structures were determined by single crystal X-ray diffraction (SCXRD). The complex crystallizes in the space group P21/c with a = 11.1022(5), b = 9.4550(5), c = 13.7613(7) Å and β = 94.035(4)°. Both adducts crystallize in the space group P with the following lattice parameters: py adduct, a = 9.1696(6) Å, b = 9.4808(9) Å, c = 11.6801(8) Å, α = 93.300(7)°, β = 108.738(6)°, γ = 100.650(7)°; and thf adduct, a = 9.1721(13) Å, b = 9.5797(13) Å, c = 11.4448(15) Å, α = 96.138(11)°, β = 106.466(12)°, γ = 101.543(12)°.
