The reaction of N , N′ ‐dialkyl‐1,2‐diaminobenzenes with bis[bis(trimethylsilyl)amido]lead(II) leads to the corresponding N‐heterocyclic plumbylenes (R = Me: 1 ; R = Et: 2 ; R = isobutyl: 3 ; R = neopentyl: 4 ). The steric demand of the N , N′ ‐dialkyl substituents determines the mode of aggregation of the plumbylenes. X‐ray diffraction analyses show both 3 and 4 to form dimers in the solid state with intermolecular [η 2 ‐(C 6 H 4 ) ··· Pb] 2 contacts for 3 and [η 6 ‐(C 6 H 4 ) ··· Pb] 2 contacts for 4 .(© Wiley‐VCH Verlag GmbH & Co.
