Compounds Based on Edge-sharing Dimers of Tetrahedra

Compounds Based on Edge-sharing Dimers of [NbAs4] Tetrahedra 

The niobium-arseitic compounds described here, with novel anionic structures, clearly demonstrate the many possibilities for stractural motifs in this system. Similarly high potential for diverse structures and properties should be expected for the heavier pitictides when combined with other transition metals and the alkali-metal group.
