Microwave assisted synthesis: A Mn/Ni reaction system affording Mn5Ni4, Mn2Ni2 and Mn7 complexes

Abstract

Following our interest in microwave assisted synthesis in coordination chemistry; we report here the results of the study of a mixed metal Mn/Ni system under common bench-top conditions and using the microwave reactor. Using bench-top, the mixed metal Mn/Ni complex Mn5Ni4(OH)4(C5H12NO)4(SALOH)6(SALO)4] (complex 1) is obtained while the microwave reactor affords a Mn7 complex, [Mn7(OH)3(C5H12NO)2(C5H13NO)(SALO)6(SALOH)3] complex 2, where the Ni(II) has not been incorporated or a Mn2Ni2 cubane, [Pr2NH2][Mn2Ni2(OH)2(C5H12NO)2(SALO)3(SALOH)2] complex 3.
