Colorless en ‐SnPO‐1, the title compound , crystallizes in the space group Pnaa and forms a network of alternating pyramidal SnO 3 and tetrahedral PO 4 moieties in which all the vertices are shared. The structure‐directing agent, diprotonated ethylenediamine, is located in an eight‐ring channel system. The Sn II lone pairs protrude into a second channel system comprising squashed twenty‐rings (see picture).
