pentevalent uranal parisar

yuu. vee. euranium kii + 5 okseekaran avastha haye joe [yuu. oh. 2] 1 + key roop mein paaee jaati haye. iss prajaati koo pentavalent uranil catayan key roop mein jaanaa jaataa haye aur tetravalent aur hexavalent euranium prajaatiyon mein anupaat key kaaran isaki sthirata cumm hoti haye. 
euranium yaugikon kii okseekaran avasthaaen + 2 seey + 6 (yuu. aaee. aaee.-yuu. vee. aaee.) taka bhinn hoti hain. inn sabhi okseekaran avasthaon mein seey + 6 sabse aam haye aur yeh [uo2] 2 + (uranil decation) key roop mein paaya jaataa haye. euranium prajaati kaa yeh shatkon roop sabse ushmaagatikiya roop seey sthir prajaati key roop mein jaanaa jaataa haye aur yeh paani mein ghulansheel haye. bhale hii euranium rasayan vigyaan kaa achchi tarah seey anveshan kiya gayaa haye, inn yaugikon kii cumm sthirata key kaaran pentavalent uranal rasayan vigyaan vikasit naheen huaa haye. praakritik roop seey paae jaane vaale dou pentavalent euranium yukt khanij hain. 
sanshleshan.
pentevalent uranil parisar uiv yaa anya cumm-valent euranium yaugikon key okseekaran dwara praapt kiye jaate hain aur yeye pratikriyaen carbonic solvents mein oxygen-mukt sthitiyon mein kii jaati hain. gair-jaleey sthitiyon yaa niyantrit jall apghatan sthitiyon key tahat yuu. aaee. aaee. aaee. aur yuu. aaee. vee. agraduton kaa okseekaran yuu. vee. vaale badey polyoxo euranium samoohon koo detaa haye. hydrothermal sanshleshan ack anya vidhi haye jiska upayog yuvi silicates praapt karane key liye kiya jaataa haye jahaan pratikriyaen 600 degree celsius jaise uchch tapman key tahat kii jaati hain.
pentevalent uranil complexes banaane kaa ack aur tarika haye [uo2] 2 + yukt uvi mein kamee. iss vidhi mein hexavalent uranil parisaron koo sthir carbonate yaa carbonic ligand kii upasthiti mein vidyut rasayanik yaa prakaash rasayanik katauti kaa upayog karke jaleey samadhanon mein yuvi parisaron mein cumm curr diyaa jaataa haye.
pentavalent uranil parisaron koo praapt karane key liye vidyut rasayanik kamee vidhi key upayog key liye ack udaaharan neeche dikhaaya gayaa haih
vibhinn β-dicatonate ligand (r = m, ph, cf3) key saath hexavalent uranal complexes kaa upayog uranal decation ([uo2] 2 +) kii iss kamee key liye kiya jaataa haye. β-dicatonate ligand kii r sthiti mein electron vaapas lene vaale pratisthapanon kii shuruat hexavalent uranil parisaron kii kamee kaa samarthan karati haye. inn vidyut rasayanik katauti key saath kiya jaataa haye 
toluen mein coca 2 ≤ yaa coca 2 aur kamee kshamata koo chakreeya voltametry kaa upayog karke maapa jaataa haye.
samanvaya rasayan vigyaan.
neeche kuchh pentevalent uranil yaugik diye gaye hain joe haal hii mein bataae gaye hain.
ack avaayaviya ghol mein [uo2] 2 + kii vidyut rasayanik kamee kaa upayog pentavalent uranil parisaron (chitra 2. yaugik 1-3) koo praapt karane key liye kiya jaataa haye. 1-4 parisaron kii samanvaya sankhya 7,7,8 aur 6 haye. yuvi key anupaat kii darr jisake parinamswarup yuvi aur uvi ph 2-4 key saath ack jaleey madhyam mein dheemi honey kii soochana haye isaliye yuvi vidyut rasayanik kamee key madhyam seey praapt kiya jaataa haye. inn yaugikon mein tetradent shiff-bases phenoxide (salophane) aur β-dicatonate ligand bhoomadhyarekhiya tala key saath bandhe hotey hain, joe uvi prajaatiyon kii ekal electron kamee seey praapt yuvi prajaatiyon koo sthir karate hain. nirjal uranil triflate yaugikon (chitra 2, yaugik 4) mein asatat cashion-aayan jode hotey hain aur yeh [uo2 (oph3) 4] [otf] 2 key kristalikaran dwara sanshleshit kiya jaataa haye. iss uranil triflet yaugik mein cashion yukt uv ack octahedral jyaamiti dikhaata haye.
khatare.
sabhi euranium yaugik radiodharmi aur vishaakt hotey hain. euranium yaugik rakt vikaar, purani gurde kii bimari, teevra tubeler necrosis, purani thakan aur janmajaat vikaaron kaa kaaran banate hain. lakshit anga gurde, yakrit, fefde aur mastishk hain. uraniel lavan neurotoxin hotey hain aur haddiyon, yakrit, gurde aur prajanan ootakon mein jamaa hotey hain. [uo2] 2 + key roop mein uvi paani mein ghulansheel honey key kaaran bhujal sandooshak key roop mein kaary kartaa haye.
