| Description | A hemipyridine solvate of bis(pyridine)silver(I) perchlorate, $[Agpy_{2}ClO_{4}$]·0.5py (compound 1) was prepared and characterized by single crystal X-ray analysis and vibrational spectroscopy (R and low-temperature Raman). Compound 1 was prepared via the trituration of $[Agpy_{2}ClO_{4}$] and $4[Agpy_{2}ClO_{4}]·[Agpy_{4}]ClO_{4}$ (as the source of the solvate pyridine) in a mixed solvent of acetone:benzene =1:1 (v = v) at room temperature. The monoclinic crystals of compound 1 were found to be isomorphic with the analogous permanganate complex (a = 19.1093(16) Å, b = 7.7016(8) Å, c = 20.6915(19) Å, β = 105.515(7)°; space group: C2/c). Two [Agpy_{2}$]^{+}$ cations formed a dimeric unit $[Agpy_{2}ClO_{4}]_{2}$, and each silver ion was connected to two ClO_{4}$^{−}$ anions via oxygen atoms. The Ag∙∙∙Ag distance was 3.3873(5) Å, the perchlorate ions were coordinated to silver ions, and the Ag∙∙∙O distances were 2.840(2) Å and 2.8749(16) Å in the centrosymmetric rectangle of Ag-O-Ag-O. The stoichiometric ratio of the monomer $[Agpy_{2}ClO_{4}$] and the solvent pyridine was 1:0.5. The guest pyridine occupied 527.2 $Å^{3}$, which was 18.0% of the volume of the unit cell. There was no additional residual solvent-accessible void in the crystal lattice. The solvate pyridine was connected via its a-CH to one of the O atoms of the perchlorate anion. Correlation analysis, as well as IR and low-temperature Raman studies, were performed to assign all perchlorate and pyridine vibrational modes. The solvate and coordinated pyridine bands in the IR and Raman spectra were not distinguishable. A perchlorate contribution via Ag-O coordination to low-frequency Raman bands was also assigned. |
