Diacetonitrile(3-{2-[8-(2-bromoethoxy)-9,10-dioxoanthracen-1-yloxy]ethyl}-1-(2-pyridylmethyl)imidazolium)silver(I) bis(hexafluoridophosphate)

Abstract

The title compound, [Ag(C27H23BrN3O4)(CH3CN)2](PF6)2, is a mononuclear salt species in which the silver(I) atom is coordinated by one ligand and two acetonitrile mol­ecules and exhibits a distorted T-shaped coordination. The asymmetric unit contains one independent cation and two independent hexa­fluorido­phosphate anions, one of which is disordered over two positions in a 0.756 (11):0.244 (11) ratio. Weak π–π inter­actions between the anthraquinone ring systems [centroid–centroid distance = 3.676 (3) Å], inter­molecular Ag–π inter­actions [Cg⋯Ag = 3.405 Å] and C—H⋯π inter­actions between pairs of adjacent mol­ecules are observed.

Silver(I) Complexes Based on Oxadiazole-Functionalized α-Aminophosphonate: Synthesis, Structural Study, and Biological Activities

“…The coordination chemistry of silver(I), which displays a [Kr] 4d 10 5s 1 electronic configuration, is particularly rich and can adopt a wide range of geometries [ 1 , 2 , 3 ]. In addition to linear silver(I) complexes [ 4 , 5 , 6 ], it is common to find triangular [ 7 , 8 ] or T-shaped [ 4 , 9 ], tetrahedral [ 10 , 11 ], or square plane [ 4 , 12 ] geometries but also compounds in which the silver atom is coordinated to five [ 13 ], six [ 13 ], seven [ 14 ], and even eight [ 15 ] ligands, often generating coordination polymers [ 16 , 17 ].…”
