Polyoxovanadium(IV) sulfite compounds: Synthesis, structural, and physical studies

An unexplored family of polyoxometalates has evolved through the synthesis and structural characterization of vanadium(IV) sulfite heteropolyanions. The hexanuclear vanadium(IV) compound, which is ferromagnetic down to 2 K, exhibits a unique structural motif for such metal species, with a central cubic {M<sub>4</sub>O<sub>2</sub>(OH)<sub>2</sub>} fragment and metal centers at two of the corners of the cluster

Copper(II) inverse-[9-metallacrown-3] compounds accommodating nitrato or diclofenac ligands: Structure, magnetism, and biological activity

Interaction of Cu(NO3)2 with phenyl 2-pyridyl ketoxime (PhPyCNOH) in the presence or absence of sodium diclofenac (Nadicl) leads to the formation of mono- or double-decker trinuclear clusters, respectively, characterized as inverse-9-metallacrown-3 accommodating dicl- or NO3- anions. The structures of [Cu3(PhPyCNO)3(μ3-O)(NO3)]2 (1) and [Cu3(PhPyCNO)3(μ3-OH)(dicl)2]·MeOH·0.5H2O (2·MeOH·0.5H2O) were determined by X-ray crystallography. Magnetic studies show a large antiferromagnetic interaction, whereas a discrepancy appears between the low-temperature magnetic data and that predicted from an isotropic Hamiltonian model, indicating the influence of antisymmetric interactions. By using a different magnetic model with antisymmetric terms, the low-temperature susceptibility and magnetization data were fitted. The EPR data support the observation that 2 has isosceles or lower magnetic symmetry, whereas the antisymmetric exchange mechanism is used to identify the reported g values of the spectra. EPR studies also revealed that complex 2 keeps its structure in solution. The complexes interact with calf-thymus DNA by intercalation. The complexes, as well as [Cu2(dicl)4(H2O)2] (3), bind to albumins with relatively high binding constants. The highest cytotoxicity of the diclofenac compounds was observed after 24 h of incubation, whereas HL-60 cells recovered after 72 h of incubation in the presence of each compound. Moreover, complex 3 was the most cytotoxic among the compounds, and complex 2 was as cytotoxic as Nadicl. Mono- and double-decker inverse-9-metallacrown-3 CuII compounds constructed with phenyl 2-pyridyl ketoxime ligands accommodating diclofenac or nitrato ligands, respectively, have been structurally characterized and their biological behavior has been evaluated in vitro. © 2016 WILEY-VCH Verlag GmbH & Co.

Facile strategies for the synthesis and crystallization of linear trinuclear nickel(II)-Schiff base, complexes with carboxylate bridges: Tuning of coordination geometry and magnetic properties

Three new linear trinuclear nickel(II) complexes, [Ni-3(salpen)(2)(OAc)(2)(H2O)(2)]center dot 4H(2)O (1) (OAc = acetate, CH3COO-), [Ni-3(salpen)(2)(OBz)(2)] (2) (OBz=benzoate, PhCOO-) and [Ni-3(salpen)(2)(OCn)(2)(CH3CN)(2)] (4) (OCn = cinnamate, PhCH=CHCOO-), H(2)salpen = tetradentate ligand, N,N'-bis(salicylidene)-1,3-pentanediamine have been synthesized and characterized structurally and magnetically. The choice of solvent for growing single crystal was made by inspecting the morphology of the initially obtained solids with the help of SEM study. The magnetic properties of a closely related complex, [Ni-3(salpen)(2)(OPh)(2)(EtOH)] (3) (OPh = phenyl acetate, PhCH2COO-) whose structure and solution properties have been reported recently, has also been studied here. The structural analyses reveal that both phenoxo and carboxylate bridging are present in all the complexes and the three Ni(II) atoms remain in linear disposition. Although the Schiff base ligand and the syn-syn bridging bidentate mode of the carboxylate group remain the same in complexes 1-4, the change of alkyl/aryl group of the carboxylates brings about systematic variations between six- and five-coordination in the geometry of the terminal Ni(II) centres of the trinuclear units. The steric demand as well as hydrophobic nature of the alkyl/aryl group of the carboxylate is found to play a crucial role in the tuning of the geometry. Variable-temperature (2-300 K) magnetic susceptibility measurements show that complexes 1-4 are antiferromagnetically coupled (J = -3.2(1), -4.6(1). -3.2(1) and -2.8(1) cm(-1) in 1-4, respectively). Calculations of the zero-field splitting parameter indicate that the values of D for complexes 1-4 are in the high range (D = +9.1(2), +14.2(2), +9.8(2) and +8.6(1) cm(-1) for 1-4, respectively). The highest D value of +14.2(2) and +9.8(2) cm(-1) for complexes 2 and 3, respectively, are consistent with the pentacoordinated geometry of the two terminal nickel(II) ions in 2 and one terminal nickel(II) ion in 3.
