A new class of N‐heterocyclic boryloxy (NHBO) ligand allows access to the first complete series of heavier Group 14 dioxycarbene analogues. Structural studies of the silylene, germylene, stannylene, and plumbylene compounds in the solid state reveal a gradual pivoting of the ligand framework to dial up arene–π interactions on going from Si (hard) to Pb (soft), as demonstrated by S. Aldridge and co‐workers in their Communication on page 4847.
