摘要
Binary metal metallocarbohedrenes of titanium and the metals yttrium, niobium, molybdenum, tantalum, and tungsten have been produced by the direct laser vaporization of mixtures of titanium carbide with these metals. Interestingly, as individuals metals, yttrium, tantalum, and tungsten have not displayed a tendency for forming the metallocarbohedrene (Met-Car) structure. Substitution of titanium atoms by these non-group IVA metals in the titanium Met-Car, Ti8C12, is not as extensive as that achieved with the group IVA metal zirconium under similar conditions. Recent theoretical predictions based upon-electronic structure and nuclear charge(8,9) 9 are considered in interpreting these results.
