The molecular structure of (Z)-2-phenyl-4-((4,6,8-trimethylazulen-1-yl)methylene)oxazol-5(4H)-one (1) was determined single-crystal X-ray diffraction. The crystal presents a monoclinic crystal system, space group P21/n, a = 7.0706(3) Å, b = 18.7978(7) Å, c = 13.7059(7) Å, β = 103.013(5) °, V = 1774.89(14) Å3. In the crystals of 1, are present strong π-π stacking interactions, with an average distance of 3.54 Å between centroids.

Reaction of Ph3Bi[O(O)CC5H4N‐3]2 (1) in CHCl3 and AgClO4 in ethanol, in 1:1 molar ratio, afforded the isolation of colorless crystals of a coordination compound which was proved to be [Ag(EtOH){Ph3Bi[O(O)CC5H4N-3]2}(ClO4)]•CHCl3 (2•CHCl3) by single-crystal X-ray diffraction. A 1D coordination polymer is formed based on bridging triphenylbismuth(V) di(nicotinate) between silver atoms, with trans Ag−N dative bonds [2.183(4), 2.196(5) Å]. Additional Ag•••O interactions are established between the coinage metal atom and an ethanol molecule [2.58(3) Å] as well as a perchlorate anion [2.746(6) Å], respectively. Its supramolecular architecture, based on a variety of non-covalent interactions, i.e. O−H•••O, C−H•••O or C−H•••Cl hydrogen bonds, π•••π , C−H•••π, C−Cl•••π interactions, as well as Ag•••O and Ag•••Cl contacts, is discussed.
