(PhCH2)5C5In^I (1) is formed in the reaction between InCl and (PhCH2)5C5Li. 1 crystallizes in the space group P2₁/c with a 1022.8(1), b 1575.3(2), c 1871.3(3) pm, β 91.01(1) deg, and V 3014.6x10^-30 m³.The crystal and molecular structure was solved to final values of R=0.025 for 5545 observed reflections with F₀>/=4?(F₀).The association of two single molecules, via a center of symmetry between the two In atoms, gives the impression of quasi- dimeric units with an In-In distance of 363.1 pm and predominantly covalent In-C bonds. 1H NMR, 13C NMR, infrared, and mass spectroscopic data are reported.
