A novel 3D network constructed from tetra-substituted trisalkoxy-hexavanadate clusters: Na2[VIV6O7{(OCH2)3CNH2}4]

Innocent or Noninnocent Interactions of the Cations on Spin-Frustrated Lindqvist Hexavanadate: Structural Analysis and Magnetic Properties

“…Thus, hexavanadate functionalized with tris(hydroxymethyl)aminomethane (TRIS-NH 2 ) can be obtained with a different number of substituents. For example, it can be obtained with four TRIS-NH 2 , 25 three TRIS-NH 2 , 26 and two TRIS-NH 2 units. 27,28 Furthermore, the tripodal alcohol can have azido or bromide substituents for postfunctionalization processes 29 and coordinating groups such as pyridine or triazole.…”
