catena-Poly[bis[dimethyl(pyridine-κN)indium(III)]-μ4-benzene-1,3-diolato-bis[dimethylindium(III)]-μ4-benzene-1,3-diolato]

The title compound, [In2(CH3)4(C6H4O2)(C5H5N)] or [{(CH3)2In}(1,3-O2C6H4){In(CH3)2(py)}]n, (py = pyridine) contains two crystallographically unique InIII ions which are in distorted tetrahedral C2O2 and distorted trigonal-bipyramidal C2O2N coordination environments. The InIII coordination centers are bridged head-to-head via In—O bonds, yielding four-membered In2O2 rings and zigzag polymeric chains along [001].
