Four noncentrosymmetric coordination polymers of [Mn((S)-imp)((R)-imp)] (1), [Cu((S)-imp)(2)](infinity) (2), [Zn((S)-imp)(2)](infinity) (3), and [Co((S)-imp)(2)](infinity) (4) [(S)-imp = (S)-2-(1H-imidazolel-yl) propionate] have been prepared and structurally characterized by X-ray single crystal diffraction, X-ray powder diffraction (XRPD), infrared (IR) spectroscopy, elemental analysis, and thermogravimetric analysis (TGA). Compound 1 crystallizes in the space group Pna2(1), exhibiting a two-dimensional structure; 2 crystallizes in the space group of P2(1), showing a chiral layered structure of (4, 4)-net, whereas 3 and 4 are isostructural, and they crystallize in the space group P2(1)2(1)2(1), exhibiting a 3-fold interpenetrating diamondoid net. Because the ligand used for the synthesis is an enantiopure chiral compound, the obtained metal organic frameworks show the homochirality in bulk except for compound 1, in which the ligand configuration was racemized during the solvothermal reaction.
