Formation of mononuclear and polynuclear <i>d</i>-block metal complexes from 1,4,7-tris(3-hydroxypropyl)-1,4,7-triazacyclononane: crystal structures, spectroscopic studies, and magnetic properties
chloride groups join two Cd(II) atoms each chelated by one triply protonated ligand H3thptacn to afford dinuclear compound 4 with a symmetry center. When coordinating to different d-blockmetals, the macrocyclic ligand exhibits four types of binding modes with various dissociation status on its pendant alcohol groups and different numbers of these pendant groups participating in coordination. The magnetic
