1,1,2,2-Tetra­kis(di-o-tolyl­phosphino)ethane

The complete molecule of title compound, C(58)H(58)P(4), is generated by a crystallographic twofold rotation axis that passes through the center of the C(methine)—C(methine) bond of length 1.582 (4) Å. The C—P bond lengths are 1.8824 (19) and 1.8991 (19) Å. The P—C—P angle of 109.69 (9)° is essentia...

description The complete molecule of title compound, C(58)H(58)P(4), is generated by a crystallographic twofold rotation axis that passes through the center of the C(methine)—C(methine) bond of length 1.582 (4) Å. The C—P bond lengths are 1.8824 (19) and 1.8991 (19) Å. The P—C—P angle of 109.69 (9)° is essentially equal to the expected value of 109.5° for a tetra­hedral C atom. Although the C(methine)—P—C(aromatic) bond angles range from 102.67 (9) to 107.04 (9)°, the C(aromatic)—P—C(aromatic) bond angles of 96.72 (9) and 97.29 (9)° are significantly smaller. The steric demands of the o-tolyl groups cause deviations from the bond lengths and angles reported for its phenyl analog.
