The structure of nitrosyltris(triphenylphosphine)rhodium, Rh(NO)‐(P(C6H5)3)3, has been determined from three‐dimensional X‐ray data. The compound crystallizes in the space group P3 of the trigonal system with three molecules in a unit cell of dimensions a = 19.057(4) and c = 10.799(2)Å. Least‐squares refinement of the 162 variables has led to a value of the conventional R index (on F) of 0.052 for the 5456 independent reflections having F2o > 3 σ (F2o). There are three independent molecules in the unit cell, one‐third of each being unique. The best first approximation is to describe the complex as a tetrahedral Rh( ‐I) complex; average parameters: Rh—P = 2.350(3), Rh—N = 1.759(13), N—O = 1.27(2) Å, P—Rh—P = 102.2(6), N—Rh—P = 116.0(5), Rh—N—O = 156.7(26)°. The nitrosyl groups are disordered about the threefold axes. The structure is compared with other metal nitrosyl phosphine complexes and the metal‐nitrosyl bonding is discussed.
