A single-crystal X-ray structure analysis of [Tc(CO){sub 3}Cl]{sub 4} is performed. The crystals belong to the cubic system, a = 10.322(3) {angstrom}, space group I{bar 4}3m, Z = 2, d{sub calc} = 2.63 g/cm{sup 3}. The crystal lattice is constructed of isolated tetrameric [Tc(CO){sub 3}Cl]{sub 4} with a cubane-like structure. The Tc(CO){sub 3} fragments are bonded to each other through Cl bridges with practically no metal-metal interaction. The total energy and bond multiplicity for [Tc(CO){sub 3}Cl]{sub 4} and the hypothetical related complexes [Tc(CO){sub 3}H]{sub 4}, [Tc(CO){sub 3}]{sub 4}{sup 4+}, and Tc{sub 4}{sup 4+} with different complex geometric parameters are calculated by the extended Hueckel method.
