The reaction of [LGa−GaL] (1) (L=dpp‐bian=1,2‐bis[(2,6‐diisopropylphenyl)imino]acenaphthene) with 4,4′‐bipyridine (4,4‐bipy) results in the formation of complex [L2(4,4‐bipy)2Ga2] (2). The reaction of 1 with 1,3‐bis(4‐pyridyl)propane (1,3‐Py2(CH2)3) affords 1D coordination polymer [L2(μ2‐1,3‐Py2(CH2)3)Ga2]n (3). Compounds 2 and 3 were characterized by 1H NMR and IR spectroscopy; their molecular structures were established by single‐crystal X‐ray analysis.
1D metal‐organic framework [L2(μ2‐1,3‐Py2(CH2)3)Ga2]n (3) was synthesized by the reaction of digallane [LGa−GaL] (1) with 1,3‐bis(4‐pyridyl)propane. Compound 3 is the first example of main group metal coordination polymer that contains redox active organic ligand besides metal−metal bond.
