Preparation, First Structure Analysis, and Magnetism of the Long-Known Nickel Benzoate Trihydrate - A Linear Ni···Ni···Ni Polymer and Its Parallels with the Active Site of Urease

Nickel benzoate trihydrate (1) has been prepared in single-crystalline form by the reaction of nickel carbonate with benzoic acid in boiling aqueous solution. Its crystal structure comprises positively charged [Ni(Bz)(H2O)2]nn+ chains, benzoate anions, and one independent water molecule of solvation. The hexacoordinate NiII centers in the chains are triply bridged by one syn-syn carboxylato and two aqua bridges, and adjacent chains are linked by O-H···O hydrogen bonds [O···O distances are in the range 2.647(3)-2.684(3) ?] through solvate water molecules and benzoate anions. Thermal analysis revealed that 1 is stable up to 100 °C; further heating led to full dehydration accompanied by an additional decomposition reaction, as characterized by IR analysis of the intermediates. The geometrical features of the Ni centers have been compared with similar features at the active sites of urease. The effective magnetic moment per formula unit μeff has a value of 3.17μB at room temperature and upon cooling reaches a maximum value of 12.39μB at T = 4.6 K, which indicates ferromagnetic coupling between the nearest NiII atoms [3.0671(1) ?] within the chains; at lower temperatures this is counteracted by zero-field splitting.

First structural and magnetic studies of Ni clusters containing 2,6-diacetylpyridine-dioxime as a ligand

In the present work, coordination possibilities of the system dapdoH 2/Ni2+, being dapdoH2 = 2,6-diacetylpyridine dioxime, have been explored, offering as a result a number of unprecedented clusters with a variety of topologies and magnetic behaviors. Depending on the precursors and reaction conditions, several compounds named [Ni 2(dapdo)2] (1), [Ni3(OH)(B2O) 3(dapdo)(dapdoH2)(H2O)]-1.25H2O (2), [Ni3(AcO)4(dapdoH)2(H2O) 2]-H2O (3), and [Ni4(AcO)3(dapdo) (dapdoH)2(H2O)3], (AcO), 3H2O (4) were achieved and structurally well-characterized. Dc magnetic measurements were carried out in the 2-300 K range revealing antiferromagnetic interactions for (2-4) compounds and diamagnetic response for the square planar coordinated complex (1).

Ni5, Ni8, and Ni10 clusters with 2,6-diacetylpyridine-dioxime as a ligand

In the present work, novel coordination possibilities for the system dapdoH2/NiII (dapdoH2 = 2,6-diacetylpyridine- dioxime) have been explored. Depending on the starting reagents and solution conditions, several clusters w
