Different but so alike are the structure of the clusters (Ph4P)2[Mn3(CO)9(S2)2(SH)] and (Ph4P)2[Mn4(CO)13(Te2)3] (E [DOUBLE BOND] S or Te; structure of the anions depicted below), which form in the reaction of [Mn2(CO)10], Na2E2, Ph4PBR, and ethanol in a sealed tube at 85°C. The fundamental difference lies in the substitution of a hydrochalcogen by a dichalcogen in the Te compound and the concomittant extension of the cluster framework by a Mn(CO)4 fragment.
