A new hybridized molecular crystal [Mn(5-MeOsaltmen)(acetone)] 2[Ni(dmit)2]6 (5-MeOsaltmen2- = N,N'-(1,1,2,2-tetramethylethylene)bis(5-methoxysalicylideneiminate), dmit 2-=2-thioxo-1,3-dithiole-4,5-dithiolate) based on [Mn] 2+2 dimer as a single molecule magnet (SMM) and the dithiolene complex [Ni(dmit)2] as a conducting part was prepared by electrochemical crystallization of (Bu4N)[Ni(dmit)2] in acetone with [Mn(5-MeOsalmen)(H2O)](PF6). An segregating stacking arrangement of the SMM layers and conducting layers is formed, where the magnetic and conducting layers involve one crystal-lographically independent [Mn]+ monomer and three [Ni(dmit)2] molecules. The SMM units were formed by dimerization of the Mn complex. Ferromagnetic exchange parameter JF in the dimeric core (1.85cm-1) can be estimated by Mn-O distance (2.298Å) in the out-of-plane dimeric core. For conducting part, overlap integral calculation between [Ni(dmit)2] acceptors in the salt suggests the existence of quasi one-dimensional interactions among the acceptors. The compound exhibits semiconducting behavior from room temperature to 50K (ρr.t=0.3ωcm, Ea=0.08eV in a crystal) without structural phase transition at ambient pressure. Then, this is a new type of conducting SMM.
