Information
has glosseng: Suboxides 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.

Meaning
German
has glossdeu: Suboxide (von lat. sub = unter) sind chemische Verbindungen des Sauerstoffs zu elektropositiveren Elementen, in denen weniger Sauerstoffatome gebunden sind, als nach der Wertigkeit des Sauerstoffs zu erwarten wären. Die formale Oxidationsstufe des anderen Elements liegt damit in diesen Verbindungen bei unter +1. Um dies auszugleichen, liegen in dieser Verbindungsklasse Element-Element-Bindungen vor. Suboxide sind vor allem von den Alkalimetallen Rubidium und Caesium, sowie Bor und Kohlenstoff bekannt.

has glosskor: 아산화물(亞酸化物)는 보통의 산화물보다 산화 정도가 한 단계 낮은 산화물을 통칭하는 말이다. 다음과 같은 화합물을 아산화물의 예로 들 수 있다. *C3O2 : 아산화 탄소 또는 이산화 삼탄소 *N2O : 아산화 질소 또는 일산화 이질소 *Cu2O : 아산화 구리 또는 산화 구리(I) *Zn2O : 아산화 아연 또는 산화 아연(I) 그러나 아산화물이라는 말은 혼동을 주기 쉽고, 산화 상태를 명확하게 나타내지 못한다는 단점이 있다. 참고문헌 *化學大辭典編集委員會 편, 성용길, 김창홍 역, 《화학대사전》, 서울: 世和, 2001.

Polish
has glosspol: Podtlenki – tlenki pierwiastków chemicznych, w których stopień utlenienia pierwiastka, wyliczony na podstawie wzoru sumarycznego, jest niższy niż jego najniższy możliwy stopień utlenienia wyższy od 0 . Tak niski stopień utlenienie wynika z występowania w jednym związku atomów jednego pierwiastka na różnych stopniach utlenienia. Np. w teoretycznym podtleneku pierwiastka X (zakładamy, że może on występować jedynie na 0 i +2 stopniu utlenienia) o wzorze sumarycznym: X2O pierwiastek X przyjmuje dwa stopnie utlenienia 0 i +2. Jednak ze wzoru sumarycznego będzie wynikało, że pierwiastek przyjął stopień utlenienia +1.
