Synthesis of Trinuclear Carbonylmanganates and Their Reaction Products with InCl3; X-ray Structure Determinations of K3[Mn3(μ-CO)2(CO)10], [(C6H5)4As]2[(μ-H)Mn3(μ-CO)10], [{(C6H5)3P}2N]2[μ-H)Mn3(CO)12], [(C6H5)4As]2[{μ-H)Mn3(CO)12}2(μ4-In)] und [(C6H5)4As]2[{(μ-H)Mn3(CO)12}(μ3-In){Mn(CO)5}Cl]Mn2(CO)10 reacts with KOH in aqueous solution to give the potassium carbonylmanganate K3[Mn3(μ-CO)2(CO)10] (1). The trianion 1 is isoelectronic with Fe3(CO)12 and is protonated with methanol to form the μ-hydrido cluster [(μ-H)Mn3;-(CO)12]3⊖, which is precipitated with [{(C6H5)3P}2N]Cl as [{(C6H5)3P}2N]2[(μ-H)Mn3(CO)12] (2), whereas the carbonyl-bridged μ-hydrido species [(μ-H)Mn3(μ-CO)2(CO)10]2⊖ seems to be trapped as the [(C6H5)4As]⊕ salt 3. The reaction of 3 with InCl3 yields the Mn-In clusters [(C6H5)4As]2[{(μ-H)Mn3(CO)12}2;-(μ4-In) (4) and [(C6H5)4As]2[{(μ-H)Mn3(CO)12}(μ3-In){Mn(CO)5}Cl] (5). X-ray structure analyses have been carried out for the compounds 1 - 5.
