Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Iridium inoumba makomputa mune oxidation nyika pakati pe - 3 ne + 9; iyo yakajairika oxidation nyika ndeye + 3 uye + 4. Mienzaniso yakanyatsotsanangurwa yeiyo yakakwirira +6 oxidation mamiriro ishoma, asi inosanganisira IrF6 uye maviri akasanganiswa oxides Sr2MgIrO6 uye Sr2CaIrO6. Mukuwedzera, zvakashumwa muna 2009 kuti iridium ((VIII) oxide (IrO4) yakagadzirirwa pasi pemamiriro ekuparadzanisa matrix (6 K muAr) ne UV irradiation ye iridium-peroxo complex. Zvisinei, rudzi urwu harutarisirwi kuva rwakavimbika sechinhu chakaoma chakasimba patembiricha dzakakwirira. Nzvimbo yakakwirira yeoxydation (+9), iyo inonyanya kunyorwa kune chero chinhu chipi nechipi, inozivikanwa chete mune imwe cation, IrO + 4; inongozivikanwa semhando yegasi-chikamu uye haizivikanwe kuumba chero munyu. Iridium dioxide, IrO2, yakasimba yebhuruu yakasviba, ndiyo chete yakanyatsotsanangurwa oxide yeiridium. A sesquioxide, Ir2O3, yakarondedzerwa seupfu hwebhuruu-nhema iyo inodyiwa kuIrO2 neHNO3. Mazita anoenderana nawo anoti disulfides, diselenides, sesquisulfides, uye sesquiselenides anozivikanwa, uye IrS3 yakataurwawo. Iridium inoitawo mairidates ane oxidation states +4 uye +5, akadai seK2IrO3 uye KIrO3, iyo inogona kugadzirirwa kubva pakuita kwe potassium oxide kana potassium superoxide neiridium pamatembiricha akakwirira. Kunyange zvazvo pasina binary hydrides yeiridium, IrxHy inozivikanwa, makomplex anozivikanwa kuti ane IrH4−5 uye IrH3−6, apo iridium ine +1 uye +3 oxidation states, maererano. The ternary hydride Mg6Ir2H11 anofungidzirwa ane zvose IrH4−5 uye 18-electron IrH5−4 anion. No monohalides kana dihalides anozivikanwa, nepo trihalides, IrX3, anozivikanwa vose halogens. Nokuda kwezviitiko zveoxydation +4 uye pamusoro, chete tetrafluoride, pentafluoride uye hexafluoride zvinozivikanwa. Iridium hexafluoride, IrF6, chinhu chinoputika uye chinoshanda zvikuru chine ruvara rutsvuku, chinoumbwa nemamolekyu eoctahedral. Inoora mumvura uye inoderedzwa kuva IrF4, chinhu chakasimba chekristaro, neiridium nhema. Iridium pentafluoride ine zvinhu zvakafanana asi chaizvoizvo iri tetramer, Ir4F20, yakaumbwa nemakona mana anogoverana octahedra. Iridium yesimbi inonyunguduka...  Mubvunzo: Maerekitironi api anofungidzirwa kuti ane ternary hydride Mg6lr2H11?
IrH4−5 uye 18-electron IrH5−4 anion
