| Description | Coordination polymers with a new rigid ligand 1,3-bis(1,2,4-triazol-1-yl)adamantane (L) were prepared by its reaction with cadmium(II) or silver(I) nitrates. Crystal structure of the coordination polymers was determined using single-crystal X-ray diffraction analysis. Silver formed two-dimensional coordination polymer $[Ag(L)NO_{3}]_{n}$, in which metal ions are linked by 1,3-bis(1,2,4-triazol-1-yl)adamantane ligands, coordinated by nitrogen atoms at positions 2 and 4 of 1,2,4-triazole rings. Layers of the coordination polymer consist of rare 18- and 30-membered ${Ag_{2}L_{2}$} and ${Ag_{4}L_{4}$} metallocycles. Cadmium(II) nitrate formed two kinds of one-dimensional coordination polymers depending on the metal-to-ligand ratio used in the synthesis. Coordination polymer $[Cd(L)_{2}(NO_{3})_{2}]_{n}$ was obtained in case of a 1:2 M:L ratio, while for M:L = 2:1 product ${[Cd(L)(NO_{3})_{2}(CH_{3}OH)]·0.5CH_{3}OH}_{n}$ was isolated. All coordination polymers demonstrated ligand-centered emission near 450 nm upon excitation at 370 nm. |
