Trimethyllead azide

Early examples of structurally characterised organolead coordination polymers with Pb—N interactions are trimethyllead cyanide, Me3PbCN335, dimethyllead dicyanide, Me2Pb(CN)2337, and trimethyllead azide, Me3PbN3 (179)467,468. The latter compound forms a linear chain polymer with a /X2-N atom symmetrically bridging the pentacoordinated lead centres [Pb—N 2.54(1) A], The N—Pb—N angle [178.6(5)°] deviates only slightly from the ideal value of 180°.

The crystal structure of trimethyllead azide, Me3PbN3, was studied. The lead atom is connected to the terminal nitrogen of the azido group, forming zigzag structures as in 8. The lead atoms exist as an almost perfect trigonal bipyramidal coordination sphere with the trimethyllead units ordered in a skew conformation. 

A number of organolead(IV) compounds are self-organized into chain structures via lead-nitrogen bonds. Such compounds include chain-like trimethyllead(IV) azide, Me3PbN3 [367, 368], triphenyllead(IV) azide, Ph3PbN3 (Pb- - -N 2.54 A) [369], trimethyllead(IV) cyanide, MesPbCN [370], triphenyllead(IV)cyanate, Ph3PbNCO (Pb-N 2.38 A, Pb-O 2.65 A [371], and dimethyllead(IV) dicyanide.
