Quadruple bridged-carbonate supported dodecanuclear [Ni₈Ca₄] coordination cluster

Abstract

A dodecanuclear [Ni8Ca4] compound, [Ni8(L)8Ca4(CO3)4(dmf)5.5(H2O)6.5]•20H2O (1) (dmf = dimethylformamide) has been prepared by the reaction of a polydentate ligand (E)-2-(2-hydroxy-3-methoxybenzylidene)amino)-4-nitrophenol (H2L) with NiCl2•6H2O, CaCl2•2H2O and Na2CO3 in dmf at room...
