 Title    The Electronic Structure o f Ternary Transition Metal Pnictides. I. AlBo-Variants  
 Abstract    The electronic structure and bonding of some ternary AlB2-type compounds AMX (A=2a-, X=5b-element, M=transition metal) were studied by means of Extended-Hückel and TB-LMTO-ASA calculations. Previous geometric stability criteria of the AIB2 structure have been extended, and reasons for some structural peculiarities and distortions are given. A simple orbital interaction scheme based on local symmetry is used as starting point to investigate the electronic properties of these compounds, whereas the band structures of the ZrBeSi-type SrPdAs and the Peierls-distorted variants CaPdAs and BaPdP are described in more detail. The results of calculations and resistivity measurements are discussed within the scope of Zintl's concept under consideration of the transition metal d-orbitals. It turns out that these solids can be described as metallic Zintl compounds.
