Pyridinium tri­bromido­stannate(II)

The crystal structure of the title salt comprises [PyH]⁺ and [Sn^IIBr₃]⁻ ions. The structural parameters of the two cations and two anions in the asymmetric unit are presented and discussed in relation to the values in other compounds. Inter­molecular inter­actions such as tetrel bonds, π–π inter­actions and N—H⋯Br hydrogen bonds are analysed.

A dinuclear silver(I) com­plex of 6-phenyl-2,2′:6′,2′′-terpyridine

A dinuclear silver(I) com­plex of 6-phenyl-2,2′:6′,2′′-terpyridine features bridging terpyridine ligands and a short intra­molecular Ag⋯Ag contact indicative of an argentophilic inter­action.

5-(4-Meth­oxy­phen­yl)-3-phenyl­iso­thia­zole

In the title compound, the dihedral angles between the central iso­thia­zole ring and pendant phenyl and p-meth­oxy­phenyl rings are 41.57 (15) and 4.63 (13)°, respectively. In the extended structure, weak C—H⋯π inter­actions may help to consolidate the packing.

6,7-Di­bromo-2-methyl-3-phenyl­quinoxaline

The title com­pound was synthesized using the acid catalyst NH₄HF₂ in a water/methanol solution.
