Accurate indium bond energies

InXn atomization energies are computed for n = 1-3 and X = H, Cl, and CH3. The geometries and frequencies are determined using density functional theo ry. The atomization energies are computed at the coupled cluster level of t heory. The complete basis set limit is obtained by extrapolation. The scala r relativistic effect is computed using the Douglas-Kroll approach. While t he heats of formation for InH, InCl, and InCl3 are in good agreement with e xperiment, the current results show that the experimental value for In(CH3) (3) must be wrong.
