Synthesis and Crystal Structure of the First Fully Characterized Vanadoborate Na3[B6O9(VO4)]

Flux growth and morphology analysis of Na3VO2B6O11 crystals

“…The experimental PXRD pattern of NVB is in good agreement with the literature data [14]. Table 1 shows the XRD result of the crystal.…”

“…Since NVB melts incongruently [14], several self-fluxes were investigated for growing NVB crystal, i.e. B 2 O 3 , Na 2 CO 3 , Na 2 CO 3 -H 3 BO 3 and Na 2 CO 3 -V 2 O 5 .…”

“…The structure of the NVB crystal was first described by Touboul et al [14]. NVB crystallizes in the orthorhombic system, space group P2 1 2 1 2 1 (no.…”

Crystal Structure of a New Form of Sodium Octoborate β-Na2B8O13

“…In order to synthesize, by a ceramic route, a sodium phosphatoborate analogous to Na 3 [B 6 O 9 (VO 4 )] sodium vanadoborate (15), a mixture of Na 2 CO 3 Á H 2 O, H 3 BO 3 and NH 4 H 2 PO 4 in 3:12:2 proportions was heated until melting at 8501C. After melting, the mixture was slowly cooled down at 0.11C/min for 501C, annealed at this temperature (8001C) for 12 h. This last process was repeated five times until a temperature of 5501C was reached.…”

Offene Gerüststrukturen von Übergangsmetallen

“…Bisher wurden keine dreidimensionalen Boratstrukturen beschrieben, die mit Amintemplaten erhalten worden wären. Die dreidimensionale Struktur von [Na] 3 [B 6 O 9 (VO 4 )] besteht aus Schichten aus Hexaborateinheiten, die durch VO 4 ‐Tetraeder verbunden sind 121a. Die Hexaboratschichten selbst können als Verknüpfung von dreieckigen BO 3 ‐ und tetraedrischen BO 4 ‐Spezies beschrieben werden.…”
