    Notes: Abstract The compounds ZR4 with R=H, CH3, and Z=C, Si, Ge, Sn or Pb have been studied in high-quality Hartree-Fock calculations. Relativistic effects have been accounted for, using the Breit-Pauli Hamiltonian and first-order perturbation theory. Relativity causes a shortening of the Z-R distance of up to 10 pm in PbH4, whereas the effect on the breathing force constant is more complex.
