2,2-dimethylpentanedioic acid (2dmepdaH2) and 3,3-dimethylpentanedioic acid (3dmepdaH2) reacted with copper(II) acetate to give [Cu(2dmepda)(H2O)3]2(1) and [Cu(3dmepda)(H2O)3]2(2). Reaction of (1) and (2) with 1,10-phenanthroline and 2,2′-bipyridine yielded [Cu(2dmepda)(phen)(H2O)]20.5phen (3), [Cu(2dmepda)(bipy)(H2O)]2(4), [Cu(2dmepda)(bipy)(EtOH)]2⋅2EtOH(4A), [Cu(3dmepda)(phen)(H2O)]2(5), and [Cu(3dmepda)(bipy)(H2O)]2⋅(6). The structures of (4A) and (6) each consists of a [Cu(bipy)(dicarboxylate)(solvent)]2dimer. The superoxide dismutase (SOD) mimetic activity of the novel copper complexes and their manganese analogues was investigated. The dimethyl sulphoxide(DMSO) soluble complexes (1)–(4) and (6) were assessed for their cancer chemotherapeutic potential towards hepatocellular carcinoma and kidney adenocarcinoma cell lines. The 1,10-phenanthroline containing complex [Cu(2dmepda)(phen)(H2O)]20.5phen (3) was the most potent with activity that compares well to that ofcisplatin.

Reactions of copper(I) acetate with 2-mercaptothiazoline (HS-thiaz) in the presence of tertiary phosphines lead to the formation of tetranuclear sulphur-bridged copper complexes. Depending on the reaction conditions, isolated clusters ([Cu4(S-thiaz)4(PR3)2] (PR3 = PPh3 (1), PEt2Ph (2), PEt3 (3)), oligomeric compounds ([Cu4(S-thiaz)4]2 (4) and [Cu4(S-thiaz)4]4 (5)), or a one-dimensional polymer ([Cu4(S-thiaz)4]∞ (6)) are formed. The structures of the compounds 2–5 have been determined by single crystal X-ray analysis.Key words: copper, 2-mercaptothiazoline, single crystal X-ray analysis.

Homoleptic Complex

We report herein the synthesis and crystal structures of five new homoleptic copper complexes of curcuminoids. The scarcity of reports of homoleptic complex structures of curcuminoids is attributed to the lack of crystallinity of such derivatives, and therefore, their characterization by single crystal X-ray diffraction is rare. The ligand design suppressing the phenolic interaction by esterification or etherification has afforded a significant increase in the number of known crystal structures of homoleptic metal complexes of curcuminoids revealing more favorable crystallinity. The crystal structures of the present new copper complexes show four-fold coordination with a square planar geometry. Two polymorphs were found for DiBncOC-Cu when crystallized from DMF. The characterization of these new complexes was carried out using infrared radiation (IR), nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR), and single crystal X-ray diffraction (SCXRD) and the antioxidant and cytotoxic activity of the obtained complexes was evaluated.
