Syntheses, Crystal Structures, and Fluorescence Properties of Cd(II), Ag( I) Complexes Based on 3,5-bis(pyridin-2-yl)-4-amino-1,2,4-triazole

Two d(10) complexes [Cd(abt)I-2(H2O)] (1) and [Ag-2(abt)(2)]2(CF3SO3) (2), (abt = 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole) have been obtained and characterized by IR, elemental analysis, and X-ray diffraction single-crystal analysis. Complex 1 is mononuclear and Cd(II) center is five coordinated, while complex 2 possesses a dinuclear structure with coordination number 4 for Ag(I) center. Solid-state fluorescence spectra of 1, 2, and abt were investigated at room temperature.
