摘要：
We examine a correlation of the melting point (Tm) and band gap ΔE of the A2TeC6 and A3B2C9 (A = K, Rb, Cs, Tl(I); B = Sb, Bi; C = Br, I) perovskite (ABC3) related halides with their average atomic number. The relationships found are interpreted in terms of the variation in the nature of chemical bonding in going from the K to Rb and Cs compounds and in terms of the key crystal-chemical features of these compounds. The results are used to predict the ΔE and Tm of compounds that have not yet been synthesized and unexplored compounds.
