The structures of the isostructural sodium, potassium, and ammonium double salts of [Co(en)3]Cl3 (en is ethane-1,2-di­amine) have been determined and, com­pared with the parent com­pound, show a modest increase in the unit-cell volume.

The tetra­mer of bis­[4-(di-n-butyl­amino)­phen­yl](pyri­din-3-yl)borane was synthesized unexpectedly and crystallized. Its structure contains an unusual 16-membered ring core made up of four (pyri­din-3-yl)borane groups. The ring adopts a conformation with pseudo-S4 symmetry that is very different from the two other reported examples of this ring system.

In the heteroleptic cuprous com­plex rac-[Cu(BINAP)(2-PhPy)]PF6, 2,2′-bis­(di­phenyl­phosphan­yl)-1,1′-binaphthyl (BINAP) and 2-phenyl­pyridine (2-PhPy) exhibit chelate and terminal coordination modes, respectively. After com­posite processing, the paper-based film based on the complex exhibits obvious luminescence light-up sensing for pyridine.

Three proton-transfer salts of di­phenyl­phosphinic acid (DPPA) with 2-amino-5-(X)-pyridine (AMPY, X = Cl, CN or CH3) have been synthesized and characterized by FT–IR and 1H NMR spectroscopy, and X-ray crystallography. Theoretical density functional theory (DFT) calculations were performed to investigate the optimized geometries and showed good agreement between the experimental data and the computational analysis.
