Organotin Phosphates Assembled from a Sterically Hindered Organophosphate, ArOP(O)(OH)₂, (Ar = 2,6-(CHPh₂)₂-4-i-Pr-C₆H₂): Syntheses and Structures

Abstract

Organotin phosphates [(n-Bu2Sn)2(LH)2(O2NO)2] (1), [(Me3­SnLH)2­(Me3­Sn­(Cl)­LH2)2]·(LH)2·8CH3OH (2), [(Me3­Sn)8­(L)4­(OH2)4]·2CH3CN (3), and [Me3­Sn­(LH)] n ·nCH3OH (4) were prepared at room temperature by the reaction of a sterically hindered ligand, 2,6-dibenzhydryl-4-isopropylphenyl dihydrogen phosphate (LH 2 ), with various organotin starting materials. Both molecular compounds [1 (dinuclear), 2 (tetranuclear), 3 (octanuclear)] and a one-dimensional coordination polymer (4) were isolated. The single crystal X-ray diffraction studies on these compounds revealed significant supramolecular interactions in their solid state mediated through a variety of secondary interactions including CHπ interactions.
