The syntheses of the intramolecularly coordinated organotin-substituted transition metal complexes [RSn{W(CO)3Cp}2][W(CO)3Cp] (2, R = 4-t-Bu-2,6-{P(O)(Oi-Pr)2}2C6H2), [RSn{W(CO)3Cp}Cl2] (4, R = 4-t-Bu-2,6-{P(O)(Oi-Pr)2}2C6H2), and [RSn{W(CO)3Cp}Cr(CO)5] (5, R = 4-t-Bu-2,6-{P(O)(OEt)2}2C6H2) are reported. The reaction of compound 2 with Ph4P+Br¯ gave the benzoxaphosphastannole [1(P),3(Sn)-Sn[W(CO)3Cp]2OP(O)(Oi-Pr)-6-t-Bu-4-P(O)(Oi-Pr)2-C6H2] (3). The compounds are characterized by 1H, 13C, 31P, 119Sn NMR and IR spectroscopy and, except for 3, by single crystal X-ray diffraction analysis. The experimental work is accompanied by DFT calculations.
