Synthesis and structure of an open-framework tin phosphate, [H3N(CH2)4NH3]0.5 2+[Sn4P3O12] −, containing intersecting channels

Abstract

A novel open-framework tin phosphate made of strictly alternating SnO 3 and PO 4 moieties contains two intersecting channels; the protonated 1,4-diaminobutane molecules are situated in one of the channels and the lone pairs of Sn II extend into the other, preventing access to the channel.
