低氧化物
Sign in to saveSuboxides are a class of oxides wherein the electropositive element is in excess relative to the “normal” oxides. When the electropositive element is a metal, the compounds are sometimes referred to as “metal-rich”. Thus the normal oxide of caesium is Cs2O, which is described as a Cs+ salt of O2−. A suboxide of caesium is Cs11O3, where the charge on Cs is clearly less than 1+, but the oxide is still described as O2−. Suboxides typically feature extensive bonding between the electropositive element, often leading to clusters.

低氧化物是一类特殊的氧化物，和相对“正常”氧化物相比，其中低电负性的元素原子个数偏多。若低电负性的元素是金属，这氧化物有时被称作“富金屬氧化物”。铯的正常氧化物是Cs2O，是由Cs+与O2−形成的氧化物。铯的一种低氧化物是Cs11O3，其中铯的氧化态显然小于+1，但氧离子依旧被认为是O2−。低氧化物的典型特征是金属—金属键，经常形成原子簇。 低氧化物的离子包括： * 低氧化碳，C3O2； * 低氧化硼，B6O； * 低氧化铷，Rb9O2； * 低氧化硅，SiOx (x < 2)
