20.500.12556/DKUM-67417 Ammoniumbis(hydroxylammonium) pentafluoridooxidovanadate(IV) synthesis and characterisation of a new fluorovanadate Turquoise crystals of a new hydroxylammonium compound with the formula $NH_4(NH_3OH)_2[VOF_5]$ have been synthesized by the reaction of solid $NH_3OHF$ and the aqueous solution of vanadium in HF. The compound crystallizes monoclinic, $P2_1/n$, with cell parameters: a = 10.5658(2) Å, b = 6.6143(1) Å, c = 11.6618(2) Å, β = 96.282(1). Magnetic susceptibility was measured using a SQUID device over a temperature range 2–300 K at magnetic field $10^3 Oe$ giving the result $µ_{eff}$ = 1.65 BM. The thermal decomposition was studied by TG and DSC analysis. $NH_4(NH_3OH)_2[OF_5V]$ decomposes above 354 K in three steps, obtaining $NH_4VOF_3$ after the first step and $V_2O_5$ as the final residue. Z reakcijo med trdnim $NH_3OHF$ in raztopino vanadija v 40% HF smo sintetizirali turkizne kristale nove spojine hidroksilamina s formulo $NH_4(NH_3OH)_2[VOF_5]$. Spojina kristalizira monoklinsko, $P2_1/n$, s parametri osnovne celice: a = 10.5658(2) Å, b = 6.6143(1) Å, c = 11.6618(2) Å, β = 96.282(1). Iz meritev magnetne susceptibilnosti z magnetometrom SQUID v temperaturnem območju 2–300 K pri magnetnem polju $10^3 Oe$ smo izračunali efektivni magnetni moment $µ_{ef}$ = 1.65 BM. Termični razkroj spojine smo spremljali s TG in DSC analizo. $NH_4(NH_3OH)_2[OF_5V]$ nad temperaturo 354 K razpada v treh stopnjah preko vmesnega produkta $NH_4VOF_3$ do končnega preostanka $V_2O_5$. hydroxylammonium fluorovanadates x-ray powder diffraction x-ray structure determination thermal analysis anorganska kemija strukturna kemija koordinacijske spojine sinteza anorganske sinteze karakterizacija spojin rentgenska strukturna določitev rentgenska difrakcija termična analiza magnetizem magnetna susceptibilnost spojine vanadija vanadati(IV) hidroksilamonijevi fluorovanadati hidroksilamin true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-08-17 10:55:17 2017-08-17 10:57:08 2022-08-01 13:57:00 2019-07-11 16:19:41 2008 0 0 str. 834-840 št. 4 Letn. 55 2008 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1318-0207 546.881.022.057:543.442.3:543.57 14086149 30084101 1318-0207 URN:SI:UM:DK:LDDRZRBV Acta_Chimica_Slovenica_2008_Dojer_et_al._Ammoniumbis_(hydroxylammonium)_Pentafluoridooxidovanadate(IV)_Synthesis_and_Characterisation_of.pdf Acta_Chimica_Slovenica_2008_Dojer_et_al._Ammoniumbis_(hydroxylammonium)_Pentafluoridooxidovanadate(IV)_Synthesis_and_Characterisation_of.pdf 1 A5EA7E29674D97E8946D32FF6A05005E e886dcdd2b3c2ddcba3006dfa269ad330c7141eba2ac1fcc97069a7a06cfd842 853d2e27-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/86612acd-10f0-412b-ad8f-3aa058e040d3 https://dk.um.si/Dokument.php?lang=slv&id=115422 http://acta-arhiv.chem-soc.si/55/55-4-834.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=115421 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
