The 4-phenylimidazole (L′H) ligand and the crystallographically determined formulae of the isolated solvatomorphs with the general composition [Cu(ClO4)2(LH)4]·x(solvent). The initially used 4-phenylimidazole ligand is present in all complexes as its 5-phenylimidazole tautomeric form (LH). MeOH = methanol, EtOH = ethanol, 1-PrOH = 1-propanol, 2-PrOH = 2-propanol, 2-BuOH = 2-butanol, DMF = dimethylformamide, Me2CO = acetone, THF = tetrahydrofuran, EtOAc = ethyl acetate, Et2O = diethyl ether . |
