• The P-P bond is a key feature in certain phosphorus-containing molecules, influencing their reactivity and stability.

Purpose of the Study:

• To elucidate the detailed molecular structure of the title compound, C(24)H(20)P(2)S.
• To characterize the P-P bond length and the spatial arrangement of phenyl rings around the phosphorus atoms.

Main Methods:

• Single-crystal X-ray diffraction analysis was employed to determine the three-dimensional structure of the molecule.
• The bond lengths and dihedral angles were precisely measured from the crystallographic data.

Main Results:

• The P-P bond length in C(24)H(20)P(2)S was determined to be 2.2263(5) Å.
• Dihedral angles of 56.22(5)° and 71.74(5)° were observed for the phenyl rings attached to the three- and five-coordinated phosphorus atoms, respectively.

Conclusions:

• The study provides precise structural data for C(24)H(20)P(2)S, contributing to the understanding of organophosphorus compounds with P-P bonds.
• The determined bond lengths and angles offer insights into the electronic and steric effects influencing the molecule's conformation.
