A new zinc phosphonate Zn(H 2 O)PO 3 –C 13 H 9 · H 2 O with a columnar structure was synthesized in hydrothermal conditions. This compound crystallizes in space group P 2 1 / c [ a = 15.832(4) Å, b = 5.1915(10) Å, c = 17.519(4) Å and β = 114.479(6)°]. Its inorganic framework consists of isolated chains of corner‐sharing ZnO 3 (H 2 O) and PO 3 C tetrahedra. These chains are linked to fluorene cycles, forming hybrid columns, interconnected through C–H ··· π bonds. The photoluminescence properties of this hybrid material show that its emission bands are red shifted with respect to those of the mother phosphonic acid. This effect is explained on the basis of the structural constraints imposed by the inorganic Zn‐phosphonate chains.
