A complete series of terphenyl-substituted 1,3-dichloro-1,3-dipnicta-2,4-diphosphanes {[ClE-(mu-P-Ter)](2), where E = P, As, Sb, or Bi and Ter = 2,6-bis(2,4,6-trimethylphenyl)phenyl} was prepared and fully characterized. While the heavy derivatives with E = Sb or Bi can be accessed via conversion of silylated phosphanes with amino-dichloropnictanes and subsequent elimination of TerNH(2), the lighter congeners could be prepared only by a metathesis reaction of [ClBi(mu-P-Ter)](2) with PCl3 and AsCl3. Spectroscopic and structural data indicate the existence of cis and trans isomers of [ClP(mu-P-Ter)](2) in contrast to all heavier derivatives, for which only the trans isomer was obtained.
