Dedicated to Professor Spyros P. Perlepes for his important contribution to inorganic chemistry on the occasion of his 65th birthday

Solvatomorphism with polar protic/aprotic and non-polar solvents in a series of complexes derived from the 5-phenylimidazole/tetrafluoroborate/copper(ii) reaction system

“…Over the last years we have prepared and studied a series of 3d metal complexes with substituted imidazole ligands to identify the trends and patterns upon which their molecular and supramolecular assembly is organized, particularly with respect to intermolecular hydrogen-bond motifs and other weak interactions. [26][27][28][29][30][31] With respect to this, we directed the present study to the use of the relatively small and flexible 4-phenylimidazole ligand (HL, Scheme 1) in combination with the tetrafluoroborate salt of copper(II). Copper(II) is an interesting and popular metal ion in coordination chemistry and has been named 'chameleon' 32 as it favours a variety of coordination numbers and geometries 33 that can be realized by properly selecting the ligands and the reaction conditions.…”

Solvatomorphism in a series of copper(II) complexes with the 5-phenylimidazole/perchlorate system as ligands

“…In recent years we have studied a series of 3d metal complexes with substituted imidazole ligands to investigate the patterns followed in the assembly process of these materials, with particular interest in the intermolecular -both strong and weak -interactions (Kounavi et al, 2009(Kounavi et al, , 2012a(Kounavi et al, ,b, 2015Kitos et al, 2016;Duros et al, 2019). With respect to this, we sought in the present study to use the relatively small and versatile 4-phenylimidazole ligand (L 0 H) in combination with the perchlorate salt of copper(II).…”
