There is good agreement between the length of the lead–lead double bond calculated for H2Pb=PbH2 and that present in the tetraaryldiplumbene 1 (R=2,4,6-iPr3C6H2), which has now been synthesized and structurally characterized. Furthermore, the calculated and experimentally observed trans bent angles Θ are similar. Thus, compounds with homonuclear double bonds between all elements of Group 14 are now known.
