Effects of lanthanide contraction and order ligand addition on the structure nuclearity [Co–Ln] aggregates along with their magnetic properties have been investigated.

in this research, structural and electronic properties of zncdn-1ten clusters (n=1-10) have been studied by formalism of density functional theory and using the projector augmented wave within local density approximation. the structural properties (such as bond length/angle and coordination number), electronic and optical properties (such as binding energy, kohn-sham spectrum and partial charge...

The first water soluble and crystallographically determined polynuclear Mn(II) complex, with water molecules bridging every two Mn centers, is reported. This is an unusual feature in 1D oligomer Mn(II) compounds with a nuclearity higher than 2. The polymer structure is largely preserved in water.

A crown-shaped organic-inorganic hybrid polyoxomolybdate, Na5[H7{N(CH2PO3)3}Mo6O16(OH) (H2O)4]4·18H2O (1) has been presented and characterized. Such an intriguing structure consists of a 24-molybdenum-membered polyanion constructed by organotriphosphonate ligands, which represents the highest nuclearity of metal atoms in the area of organophosphonate-based polyoxometalates.

Comproportionation reactions between MnCl2 and KMnO4 in the presence of arsonate or phosphonate ligands promote the cation-assisted assembly of high-nuclearity, wheel-shaped or toroidal {Mn8} () and {Mn24} () complexes; the closely corresponding reaction systems provide insights into the complexation behaviour of homologous phosphonate/arsonate ligand species.

Dissolution of a mononuclear complex [Zn(dmpzdtc)2] in BrCH2CH2Br or DMF saturated with water followed by CS2 elimination led to the formation of two unique high-nuclearity metallamacrocyclic complexes, [Zn4(micro-dmpz)6(micro-OH)2]2 and [Zn4(micro-dmpz)6(micro-OH)2]4.

Structurally diverse mononuclear, dinuclear, and tetranuclear cobalt organophosphates and a three-dimensional framework based on a D4R cobalt phosphate are reported. The role of auxiliary ligands in determining the nuclearity of the phosphate clusters has further been established. Reaction of cobalt acetate tetrahydrate with 2,6-di-iso-propylphenylphosphate (dippH2) in methanol or DMSO in the p...
