Triphenylphosphine and triphenylarsine derivatives of W(CO)4(NO)X (X = Cl, Br, I) have been prepared. These compounds have the form mer- W(CO)3(NO)LX, cis-W(CO)2(NO)L2X, and trans-W(CO)2(NO)(PPh3)2X. A trans complex with triphenylarsine could not be prepared. Further substitution with either ligand was not achieved. In addition, the tri(ortho-, meta-, and para-)tolylphosphine and arsine complexes of W(CO)4(NO)I have been isolated. Their nuclear magnetic resonance spectra indicate interaction between neighbouring ligands in some cases, and suggest that possible rotation about the metal-phosphorus and arsenic bonds may occur in these compounds.
