Coordination Chemistry and Methylation of Mixed‐Substituted Tetraphosphetanes (RP−PtBu)₂ (R=Ph, Py)

Choose your coordination site! The cover art (DOI: 10.1002/chem.202003226 ) shows a beautifully handcrafted puzzle by Sina Krol featuring a mixed‐substituted tetraphosphetane with two pyridyl‐substituents. In particular, the presence of soft and hard donor atoms (N, P) allows for the coordination of selected coinage metal salts and an intriguing methylation chemistry with methyl triflate, involving rare P−P/Py−P bond metathesis.
