AbstractA new zinc(II)-based coordination polymer {[Zn(5-fip)(tdbpy)]·(DMF)}n (1) {5-H2fip=5-fluoroisophthalic acid, tdbpy=4,4′-(2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-diyl)bispyridine, DMF=dimethylformamide} has been solvothermally synthesized and structurally characterized. Single-crystal X-ray diffraction revealed that complex 1 shows a unique two-dimensional network architecture containing single-stranded [Zn(5-fip)]n and double-stranded helical [Zn(tdbpy)]n chains. The thermal and luminescence properties of complex 1 have also been studied.

The title compound, (S)-pyrrolidine-2-carboxylic acid (C5H9NO2), commonly known as L-proline, crystallized without the inclusion of any solvent or water molecules through the slow diffusion of diethyl ether into a saturated solution of L-proline in ethanol. L-Proline crystallized in its zwitterionic form and the molecules are linked via N—H...O hydrogen bonds, resulting in a two-dimensional network. In comparison to the only other publication of a single-crystal structure of L-proline without inclusions [Kayushina & Vainshtein (1965). Kristallografiya, 10, 833–844], the R 1 value is significantly improved (0.039 versus 0.169) and thus, our data provides higher precision structural information.
