Silver-gadolinium polytetraphosphate AgGd(PO3)4 synthesis, structural study, IR spectroscopy and conductivity investigation

A new Rubidium - Bismuth polyphosphate RbBi(PO3)4: Growth, X-ray single crystal and vibrational study

“…The helical (PO3)n chains in the RbBi(PO3)4 structure, are similar to those of the other alkaline lanthanide polyphosphates [19][20][21], in which the chains run along the longest unit-cell directions as shown in Figure 2. The polytetraphosphate anion is, as usual in the same group; make up of a chain of eight tetrahedra PO4 sharing corners.…”

Magnetic and Photon Cascade Emission of Gd3+ of NaGd(PO3)4 Monocrystal Under Appropriate Synthesis Conditions

“…The analysis of the Raman spectra is based on the comparison with homologous compounds [21][22][23] and at the same time with the calculated frequencies of the chain Figure 4 we can be simply observed that NaGd(PO 3 ) 4 Raman spectra is dominated by two well and intense bands at 696 cm -1 and 1184 cm -1 , they are assigned respectively, to the symmetric stretching vibration modes of (P-O-P) and (O-P-O) -. Those bands are characteristic of long chain polyphosphates, so we can therefore confirm that NaGd(PO 3 ) 4 crystallize in chain structure.…”

Redetermination of AgPO3

“…Properties of glassy silver phosphates have been reported by Portier et al (1990) and Novita et al (2009). For long-chain polyphosphates AgM III (PO 3 ) 4 (M III = La, Gd, Eu), see: El Masloumi et al (2005); Naıli et al (2006); Ayadi et al (2009). For AgM II (PO 3 ) 3 (M II = Mg, Zn, Ba), see: Belharouak et al (1999); for AgM I (PO 3 ) 2 (M I = K, Rb, Cs, Tl), see: Averbuch-Pouchot (1993).…”
