Secondary title: synthesis and characterisation of a new fluorovanadate
Secondary abstract: 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 $V_2O_5$.
