Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: Iridium yana samar da mahadi a cikin yanayin hadawan abu da iskar shaka tsakanin -3 da +9; yanayin hadawan abu da iskar shaka na yau da kullun shine +3 da +4. Misalai masu kyau da aka kwatanta da yanayin haɓakar +6 mai yawa ba safai ba, amma sun haɗa da IrF6 da kuma oxides guda biyu Sr2MgIrO6 da Sr2CaIrO6. Bugu da ƙari, an ba da rahoto a cikin 2009 cewa an shirya iridium ((VIII) oxide (IrO4) a ƙarƙashin yanayin keɓewar matrix (6 K a cikin Ar) ta hanyar hasken UV na hadaddun iridium-peroxo. Wannan nau'in, duk da haka, ba a tsammanin zai kasance mai karko a matsayin babban abu a yanayin zafi mafi girma. Mafi girman yanayin hadawan abu da iskar shaka (+9), wanda kuma shine mafi girman da aka rubuta ga kowane abu, an san shi ne kawai a cikin wani cation, IrO + 4; an san shi ne kawai a matsayin nau'in gas-phase kuma ba a san shi da samar da wani gishiri ba.Iridium dioxide, IrO2, wani abu mai launin shudi mai launin shudi, shine kawai oxide na iridium da aka kwatanta da kyau. An bayyana wani sesquioxide, Ir2O3, a matsayin foda mai launin shuɗi-baki wanda HNO3 ya oxidized zuwa IrO2. Abubuwan da suka dace da disulfides, diselenides, sesquisulfides, da sesquiselenides an san su, kuma an kuma ba da rahoton IrS3. Iridium kuma yana samar da iridates tare da yanayin oxidation +4 da +5, kamar su K2IrO3 da KIrO3, wanda za'a iya shirya shi daga halayen potassium oxide ko potassium superoxide tare da iridium a yanayin zafi mai zafi. Kodayake babu wani binary hydrides na iridium, IrxHy da aka sani, an san abubuwan da ke dauke da IrH4−5 da IrH3−6, inda iridium ke da yanayin oxidation na +1 da +3, bi da bi. An yi imanin cewa ternary hydride Mg6Ir2H11 ya ƙunshi duka IrH4−5 da 18-electron IrH5−4 anion. Babu monohalides ko dihalides da aka sani, yayin da aka san trihalides, IrX3, ga duk halogens. Don jihohin hadawan abu da iskar shaka +4 da sama, kawai tetrafluoride, pentafluoride da hexafluoride ne aka sani. Iridium hexafluoride, IrF6, mai saurin tashi ne kuma mai saurin amsawa mai launin rawaya, wanda ya kunshi kwayoyin octahedral. Yana narkewa a cikin ruwa kuma an rage shi zuwa IrF4, mai daskararren crystalline, ta hanyar iridium baƙar fata. Iridium pentafluoride yana da irin wannan kaddarorin amma a zahiri tetramer ne, Ir4F20, wanda aka kafa ta octahedra huɗu masu raba kusurwa. Iridium ƙarfe ya narke...  Tambaya: Mene ne electrons cewa ternary hydride Mg6lr2H11 an yi imani da cewa dauke da?
