Synthesis and crystal structures of [Ph₃PCH₂PPh₃]I₂ di-chloro-methane disolvate and [Ph₃PCH₂PPh₃](BI₄)₂.

ABSTRACT: Reaction of BI₃ with carbodi-phospho-rane, C(PPh₃)₂, gives a mixture of the dicationic compounds, methyl-enebis(tri-phenyl-phospho-nium) diiodide di-chloro-methane disolvate, C₃₇H₃₂P₂²⁺·2I^-·2CH₂Cl₂ or [Ph₃PCH₂PPh₃]I₂·2CH₂Cl₂ (I), methyl-enebis(tri-phenyl-phospho-nium) bis-(tetra-iodo-borate), C₃₇H₃₂P₂²⁺·2BI₄^- or [Ph₃PCH₂PPh₃](BI₄)₂ (II). Solvents are the source of the protons at the ylidic C atom. The P-C-P angle is 124.1 (2)° for (I) and 121.7 (3)° for (II), while the t
