Dimethyllead dicyanide

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°. 

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.
