Synthesis, crystal structure and spectroscopic studies of a new silver complex derived from [1-(3-pyridinyl) ethanone]

•Synthesis and complete characterization of the new complex [Ag(1-(3-pyridinyl) ethanone)2(H2O)](NO3).•X-ray crystallographic analysis of the Ag(I) complex.•FMO and MEP of complex were calculated and discussed.•Hirshfeld surface analysis suggest hydrogen bonding as crucial for packing. In this work, a new silver (I) complex, [Ag(3-pye)2(H2O)](NO3) where 3-pye=1-(3-pyridinyl) ethanone, has been synthesized and characterized by elemental analyses, FT-IR, fluorescence spectroscopy, and single X-ray crystallography. The X-ray diffraction analysis revealed that the Ag(I) complex crystallized in the monoclinic system with the C2/c space group. Computational studies were performed using DFT approache on the present complex to get insight into the structural parameters, spectral characteristics and electronic properties. The characterization results were found to be consistent with the proposed structure of the complex, and the DFT approach supported the experimental results. Also, Hirshfeld surface analysis was used to identify the non-covalent interactions within the crystal structure as well as to visualize the conformity of the crystal structure. [Display omitted]
