Abstract—The zinc O,O'-di-iso-propyl phosphorodithioate complex [Zn₄O{S₂P(O-iso-C₃H₇)₂}₆] (I) has been
synthesized and characterized by multinuclear MAS NMR (¹³C, ³¹P). The metal core of the tetranuclear struc-
ture 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 ₂ bridges combining pairs of zinc atoms. Bonding of all metal
atoms to the ₄ oxygen atom provides additional stabilization of the structure. For ³¹P NMR signals, the chem-
ical shift anisotropy _aniso and the asymmetry parameter were calculated, which allowed to assign them to the
phosphorus positions in the structure of I.
