Abstract

Hydrothermal Synthesis and Characterization of Two-and Three-Dimensional Solids of the Oxovanadium(IV)-Phosphite System. The Structures of [HN(Me)(CH2CH2)2N(Me)H]-[(V0)4(0H)2(HP03)4], [H2N(CH2CH2)2NH2][(V0)3(HP03)4(H20)2], and [V0(HP03)(H20)]

(H3NC2H4NH3)[In(OH)3(HPO3)]: the first organically templated indium phosphite

“…The P atom adopts psuedo-pyramidal coordination geometry, which is coordinated to three O atoms with bond lengths of 1.515(4) Å for P-O1, 1.509(4) Å for P-O4 and 1.515(4) Å for P-O5, respectively, thus there are no terminal, ''pendant'' P-O or P-OH bonds [9], and a P-H bond makes up the fourth vertex of each [HPO 3 ] 2À tetrahedron. The terminal P-H bond length is 1.34(4) Å which is similar to the P-H bond length reported in H 3 PO 3 previously [3]. The existence of P-H bond is also verified by IR spectrum, which exhibits strong absorption at 2397 cm À1 [4].…”

“…It is well known that the pyramidal hydrogen phosphite group ½HPO 2À 3 , different from phosphate ½PO 3À 4 , only link three adjacent cations via P-O-M (M = metal) bonds, so it provides variety and novelty to the structures. Since the vanadium phosphites with piperazinium cations as structurally directing agents [H 2 NC 4 H 8 NH 2 ][(VO) 3 (HPO 3 ) 4 (H 2 O) 2 ] were synthesized by Zubieta and co-workers [3], a number of studies on the metal phosphites containing Zn, Co, Fe, V, Mn and Cr have been carried out [4] [6] have been reported. Some of microporous indium phosphates containing organically templates have been prepared [7], but the indium phosphites are under developed.…”

“…In atom adopts six coordination geometry, where three are bridging oxygen atoms from the adjacent P atoms with In-O1, In-O4 and In-O5 bond lengths being 2.105(4), 2.106(3) and 2.095(4) Å , respectively, and the other three from hydroxy groups. Bond valence calculations [8] 3 ] unit has distorted octahedral geometry which due to the different coordination strengths of O 2À and OH ligand. The P atom adopts psuedo-pyramidal coordination geometry, which is coordinated to three O atoms with bond lengths of 1.515(4) Å for P-O1, 1.509(4) Å for P-O4 and 1.515(4) Å for P-O5, respectively, thus there are no terminal, ''pendant'' P-O or P-OH bonds [9], and a P-H bond makes up the fourth vertex of each [HPO 3 ] 2À tetrahedron.…”

(C6H17N3)[Zn4(PO4)2(HPO3)2]: a new layered zinc phosphate–phosphite templated by 1-(2-Aminoethyl) piperazine

“…has attracted considerable attention [10][11][12][13]. Harrison et al [14] reported the first organically templated zincophosphite.…”

Hydrothermal synthesis, crystal structures, and magnetic properties of a novel three-dimensional iron phosphite:

“…Following the initial reports on several novel transition metal phosphites (e.g., the organically templated vanadium phosphites [2]), manganese phosphites [3,4], cobalt phosphite [5], and zinc phosphites [6][7][8] the replacement of phosphate with phosphite in the transition metal phosphates has attracted more and more research efforts. Our group has developed the hydrothermal synthesis of many novel metal phosphites [9][10][11].…”
