There is an increasing demand for novel metal-based complexes with biologically relevant molecules in technology and medicine. Three new Cu (II) coordination compounds with antifungal agent isoconazole (L), namely mononuclear complexes [CuCl2 (L) 2](1), and [Cu (O2CMe) 2 (L) 2]· 2H2O (2) and coordination polymer [Cu (pht)(L) 2] n (3)(where H2pht–o- phthalic acid) were synthesized and characterized by IR spectroscopy, thermogravimetric ...
