Molecular structures of [InI3(bipy)6]3+ (43+), [InI3(bipy)5]3+ (53+) and [InI3(bipy)6]4+ (64+). Selected bond lengths are given in pm and angles in °: 43+, In1−In2=266.07(4), In1−In3=266.98(5), In2−In3=278.12(5), av. In1−N=236.9(4), av. In2−N=249.0(4), av. In3−N=246.5(4) and ∢(In−In−In)=58.39(12)−62.90(12); 53+, In1−In2=267.89(5), In1−In3=266.80(5), In2−In3=269.84(5), av. In1−N=233.8(4), av. In2−N=234.0(4), av. In3−N=235.3(4) and ∢(In−In−In)=59.49(14)−60.62(14) (the asymmetric unit of 5 contains a second [InI3(bipy)5]3+ cluster featuring similar bonds lengths, Supplementary Table 4); 64+, In1−In2=275.93(14), In1−In3=259.65(12), In1−In4=276.62(14), In2−In3=280.83(14), In3−In4=278.56(14), av. In1−N=232.40(10), av. In2−N=236.33(10), av. In3−N=233.60(10), av. In4−N=236.10(10) and ∢(In−In−In)=55.59(3)−63.16(4) (the asymmetric unit of 6 contains four [InI4(bipy)6]4+ clusters, featuring similar In−In bonds lengths, Supplementary Table 5). The [Al(ORF)4]– anions and all of the hydrogen atoms were omitted for clarity. The thermal ellipsoids are set at 50% probability. An alternative representation, featuring ellipsoids for all atoms, is included in Supplementary Fig. 6.
