The phospha-arsa-mangana-cyclopropane (OC)4Mn–PPh2–AsAr (4) [Ar = 2,4,6-(t-Bu)3C6H2] is obtained in a one-pot reaction proceeding in the sequence Mn2(CO)10 → HMn(CO)5 (1) → HMn(CO)4PPh2H (2) → Li2[(OC)4Mn—⃛PPh2] (3) → 4. According to an X-ray structural analysis 4 has a short P–As bond (229 pm) and a long Mn–As distance (262 pm).
