Donor stabilization of Sn(II) and Pb(II) halides with 1,1’-ferrocenylene bridged bisphosphanes has been explored for Fe(C₅H₄P(C6H₅)₂)₂ (dppf), and Fe(C₅H₄PH(C₄H9))₂. These bisphosphanes are reacted with SnBr₂ and PbCl₂ with and without additional Lewis acid (AlCl₃) forming acyclic and cyclic donor adducts from which the latter represent bisphosphoniotetrylenes. Since dynamic exchange in solution is observed, characterization includes solution and solid-state NMR in addition to SC-XRD, amended by DFT calculations.
