...Even in compounds with stoichiometric compositions, metals often do not take their normal atomic valences as a result of forming a crystal lattice different from that of the original crystal (e.g., hydrides of chromium, zirconium, and iron CrH, ZrH, FeH 6 , etc.). In addition, there are intermediate hydrides between salt-like and volatile hydrides, such as hydrides of germanium, silicon, and indium GeH 4 , SiH 4 , InH 3 , and alkyl metal hydrides formed by the decomposition of alkyl metal compounds, such as hydrides of nickel, cobalt, and copper NiH 2 , CoH 2 , CuH.

…化学量論的組成をもつ化合物でも,もとの結晶とは異なった結晶格子をつくる結果,金属がふつうの原子価をとらない場合が多い(クロム,ジルコニウム,鉄の水素化物CrH,ZrH,FeH6など)。このほかにゲルマニウム,ケイ素,インジウムの水素化物GeH4,SiH4,InH3などのように塩類似型と揮発性水素化物との中間的なもの,ニッケル,コバルト,銅の水素化物NiH2,CoH2,CuHなどのようにアルキル金属化合物の分解によって生ずるアルキル金属型水素化物などもある。【大滝 仁志】。… ※「アルキル金属型水素化物」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
