Synthesis, Crystal Structure and DFT Studies of a New Dinuclear Ag(I)-Malonamide Complex.

ABSTRACT: The synthesis and structural aspects of a new dinuclear silver (I) complex with malonamide type ligand (L) is reported. Each Ag ion in the [Ag₂L₂(NO₃)₂]·H₂O complex is coordinated to two ligands, L, each acting as a bridged ligand via its two pyridine arms; Ag(I) acts as a connector between them. Two types of Ag-ligands close contacts were detected: Ag-N1, Ag-N4 from the two L units, and Ag-O5, Ag-O6 from the two nitrate anions, wherein both the nitrate ions are inside the cage formed by the [Ag₂L₂] unit. The coordination geometry around each Ag(I) is a distorted tetrahedron. The [Ag₂L₂(NO₃)₂] complex units are connected by weak intermolecular C-H…O interactions. The different intermolecular interactions were quantified using Hirshfeld surface analysis. Using two DFT methods (B3LYP and WB9
