dc.description.abstractReaction of BI3 with carbodi­phospho­rane, C(PPh3)2, gives a mixture of the dicationic compounds, methyl­enebis(tri­phenyl­phospho­nium) diiodide di­chloro­methane disolvate, C37H32P22+·2I−·2CH2Cl2 or [Ph3PCH2PPh3]I2·2CH2Cl2 (I), methyl­enebis(tri­phenyl­phospho­nium) bis­(tetra­iodo­borate), 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 two P—C bond lengths are 1.804 (4) and 1.807 (5) Å in (I), and 1.817 (5) and 1.829 (5) Å in (II). In the crystal of (I), the protons of the central P—CH2—P C atom exhibit weak C—H...I hydrogen bonds with the respective anions. The anions in turn are linked to the di­chloro­methane solvent mol­ecules by C—H...I hydrogen bonds. In the crystal of (II), one of the BI4− anions is linked to a phenyl H atom via a weak C—H...I hydrogen bond.en_US
