Abstract
Triphenyltin chloride reacts with equimolar amounts of tetramethylammo nium chloride and of silver oxalate to yield tetramethylammonium bisox alatotris(triphenylstannate). A crystal structural study has shown the trinuclear stannate to be composed of helical [Ph3Snox.(Ph3Sn)2ox]nn- chains that run parallel to the b-axis; the cations fill up the space between the chains. The structure is an unusual example of a triorgan otin compound having within the same molecule five-coordinate tin site s in distinct cis- and trans-trigonal bipyramidal geometries.
