Extending this approach to bridging ligands beyond bi/polycarboxylates, poly- [26,[33][34][35][36] Results and Discussion…”

Cu^II Frameworks from Di‐2‐pyridyl Ketone and Benzene‐1,3,5‐triphosphonic Acid

Abstract:In our effort to develop new synthetic strategies for the isolation of new phosphonate frameworks, we exploited the possibility of simultaneously utilizing benzene-1,3,5-triphosphonic acid (H 6 btp) and di-2-pyridyl ketone (py 2 CO), which is a major player in the field of polynuclear metal complexes. This ligand blend in Cu II chemistry afforded a 2D framework comprising tetranuclear [Cu

“…[8] The dpk ligand is extremely versatile since it has the ability to chelate through multiple donor sites. It is capable of behaving as a bidentate or tridentate ligand chelating through N,N, N,O, or N,N,O donor atoms respectively, [1,2] and when coordinated to a metal centre the ketone C=O group is susceptible to nucleophilic addition. Subsequently, dpk can transform to a chemically modified ligand through in situ processes, which are not readily achieved through conventional organic methods.…”

“…The hydrated/alcoholated dpk derivative. [2,9] The hydrated and alcoholated derivatives of dpk are quite common; recently however more interest has developed for other nucleophiles to attack the ketone carbonyl. [8] In situ cyanomethylation of the carbonyl group on dpk was observed on reaction of a divalent metal salt with dpk in the presence of a catalytic base, [11] and Abrahams et al [12] have observed nucleophilic attack with bisulfite, and pyrazole.…”

Complexes containing di(2‐pyridyl) ketone (dpk) as a bi‐ (N,N) and tridentate (N,N,O) ligand have been synthesised1,2 and characterized by spectral and structural studies. Products 1 and 2 are polymorphs of the polymeric copper(I) complex [Cu(dpk)(NCS)]n containing dpk with thiocyanate anions which bridge to form a one‐dimensional continuous polymer chain. The novel dinuclear copper(II) complex [Cu2(dpk·acetone)2(NCS)2] (3) was formed when 1 and 2 were allowed to stand in the supernatant. In this instance it appears that a transition‐metal‐promoted aldol condensation has occurred between the solvent acetone and the ketone carbonyl of dpk to produce the novel ligand, dpk·acetone. Product 3 contains two five‐coordinate copper(II) ions, both with trigonal bipyramidal coordination, bridged through deprotonated hydroxy groups on each dpk·acetone. A chemical rationalisation for the formation of 3 is proposed. The dinuclear copper(I) complex [Cu2(dpk)2I2] (4) is also reported, which contains two four‐coordinate copper(I) ions that are bridged together through iodide ions.

“…Usually, the mono-and dianion derivatives of the gem-diols and the monoanion of the hemiketals can bridge two or more metal ions. [28,29] In related recently published papers, [31,32] several dpk-Rphosphonic copper(II) derivatives have been reported (R = tertbutyl). Here, we report the structural characterization and the magnetic behavior of two new copper(II) dpk-Rphosphonic complexes: mononuclear [Cu{(py) 2 C(OH) 2 Figure 1).…”

The syntheses, structural characterization, and magnetic behavior of five new copper(II) complexes derived from phosphonoacetic acid, H2O3PCH2CO2H, with the formulae [Cu{(py)2C(OH)2}](HO3PCH2CO2H)2 (1), [Cu2(HO3PCH2CO2)2{(py)2C(OCH3)OH}2] (2), [Cu2(HO3PCH2CO2)2(bpy)2] (3), [Cu4(O3PCH2CO2)2(5‐dmbpy)4(H2O)4](NO3)2 (4), and [Cu4(O3PCH2CO2)2(5‐dmbpy)4(H2O)4](ClO4)2 (5) are reported. [H2O3PCH2CO2H = phosphonoacetic acid, (py)2C(OH)2 = bis(2‐pyridyl)methanediol, {(py)2C(OCH3)OH} = bis(2‐pyridyl)methoxymethanol, bpy = 2,2′‐dipyridyl, 5‐dmbpy = 5,5′‐dimethyl‐2,2′‐dipyridyl, terpy = 2,2′:6′,2″‐terpyridine]. Complex 1 is a mononuclear compound with hydrogenphosphonateacetic acid in its monoanionic form, complexes 2 and 3 are dinuclear compounds with hydrogenphosphonoacetate(2–) bridging ligands, and complexes 4 and 5 are tetranuclear compounds with phosphonoacetate(3–) bridging ligands. The magnetic properties of polynuclear complexes 2–5 are reported.
