چکیده

This work addresses and enlightens synthetic aspects derived from our effort to systematically construct isoskeletal tetranuclear coordination clusters (CCs) of the general formula [TR2Ln2IJLX)4IJNO3)2IJsolv)2] possessing a specific defected dicubane topology, utilizing various substituted Schiff base organic ligands (H2LX) and Ni /Co and DyIJOTf)3 salts. Our synthetic work is further supported by DFT studies.

Constructing octa- and hexadecanuclear manganese clusters from tetrahedral Mn(III)(3)Mn(II) cores bridged by quinquedentate Schiff base and versatile azide groups.

Reactions of MnX(2) meltsalt (X = Cl and ClO(4)) and a quinquedentate Schiff base ligand together with its coligand azides in MeOH produced the unprecedented assembly of novel octa- and hexadecanuclear manganese clusters containing two and four alternant tetrahedral Mn(III)(3)Mn(II) cores bridged by Schiff base ligands and versatile azides groups. The magnetic measurements on both compounds ind...
