ChemInform Abstract: The First Three‐Dimensional Vanadium Hypophosphite.

Abstract

Vanadium I 5000The First Three-Dimensional Vanadium Hypophosphite. -The new anhydrous vanadium hypophosphite V(H 2 PO 2 ) 3 is prepared by hydrothermal reaction of V 2 O 5 and H3PO2 in the presence of Li2CO3 (H2O, 423 K, autoclave, 48 h). The compound crystallizes in the monoclinic space group P21/n with Z = 4. The structure is based on VO6 octahedra and H2 pseudo-tetrahedra, which are connected to [VPO6 ] chains extending along all three crystallographic axes and thus form a three-dimensional network. -(MAOUEL*, H.

[Am]Mn(H2POO)3: A New Family of Hybrid Perovskites Based on the Hypophosphite Ligand

“…18 We also note the existence of V(H 2 PO 2 ) 3 , which has the parent reo topology. 19 Using the Goldschmidt tolerance factor modified for hybrid perovskites, 20,21 we predicted compositions likely to adopt the perovskite structure when X = hypophosphite. We then succeeded in synthesizing perovskites with five different Asite amine cations: guanidinium (GUA), formamidinium (FA), imidazolium (IM), triazolium (TRZ), and 1,4diazabicyclo[2.2.2]octane-1,4-diium or "DABCOnium" (DAB) (see Supporting Information for details).…”
