摘要：

In Ba7Ga4Sb9, a recently synthesized compound, there is a Ga4Sb,14- two-dimensional net that probes the limits of the Zintl concept. It is made up of one-dimensional alternating four- and eight-membered Ga-Sb rings, linked together into a two-dimensional structure by long but bonding Sb-Sb contacts. Band calculations reveal quite localized bonding and a half-filled Sb-Sb σ* band. A pairing distortion is indicated and should be sought experimentally. © 1990, American Chemical Society.
