Abstract
The zinc O,O’-di-iso-propyl phosphorodithioate complex [Zn4O⨑ub;S2P(O-iso-C3H7)2⫂ub;6] (I) has been synthesized and characterized by multinuclear MAS NMR (13C, 31P). The metal core of the tetranuclear structure of I, determined by single-crystal X-ray diffraction, is a tetrahedron centered by an oxygen atom. All Dtph ligands are structurally nonequivalent and act as μ2 bridges combining pairs of zinc atoms. Bonding of all metal atoms to the μ4 oxygen atom provides additional stabilization of the structure. For 31P NMR signals, the chemical shift anisotropy δaniso and the asymmetry parameter η were calculated, which allowed to assign them to the phosphorus positions in the structure of I.
