A new fluorinated gallium phosphite, Ga{sub 3}F{sub 2}(2,2'-bipy){sub 2}(HPO{sub 3}){sub 2}(H{sub 1.5}PO{sub 3}){sub 2}1, which is the first layered gallium phosphite with neutral framework, has been hydrothermally synthesized in the presence of 2,2'-bipyridine (2,2'-bipy) acting as a ligand. The as-synthesized product was characterized by single-crystal X-ray diffraction, powder X-ray diffraction, IR spectroscopy, thermogravimetric analysis (TGA), ICP-AES and elemental analyses and fluorescent spectrum. Single-crystal X-ray diffraction analysis reveals that compound 1 crystallizes in the monoclinic space group C2/c (No. 15) with cell parameters a=17.633(3) A, b=9.883(2) A, c=16.793(3) A, {beta}=109.88(3){sup o}, V=2752.1(9) A{sup 3} and Z=4. The construction of two-dimensional (2D)-layered structure in compound 1 may be viewed as the assembly of heptameric building unit, which is the first to be found in gallium phosphate/phosphite. The heptameric building unit exists in two types of configuration, which alternately connect through oxygen atoms from HPO{sub 3} pseudo-pyramids to form a layer with 10-membered ring windows viewed along the a-axis. The adjacent layers are stably packed together and exhibit interesting three-dimensional (3D) supramolecular array via {pi}-{pi} interactions of the 2,2'-bipy groups. Additionally, compound 1 shows strong fluorescent property in solid state at room temperature. - Graphical abstract: The first two-dimensional layer gallium phosphite Ga{sub 3}F{sub 2}(2,2'-bipy){sub 2}(HPO{sub 3}){sub 2}(H{sub 1.5}PO{sub 3}){sub 2} with 10-membered ring windows along the a-axis, which is built from the novel heptameric building unit.
