(Top) The Sm2 cations of each metal chain are linked to a neighboring metal chain via the di-CMPO organic ligands. Color codes: black C, light green Sm1, dark green Sm2, red O, blue N, and orange P. (Bottom) The metal chain showing alternating Sm1 and Sm2 cations, linked through bridging bis-bidentate nitrate groups shown in pink. Non-bridging nitrate groups are shown in purple. Hydrogen bonds between the water molecule on Sm2 and nitrate groups on Sm1 are shown as dashed lines. |
