Hydrothermal synthesis and structures of the homoleptic iodate complexes [M(IO3)6]2− (M = Mo, Zr)

CsAlZr2(PO4)4: an anhydrous aluminium zirconium phosphate with a novel three-dimensional framework

“…1 illustrates a selected unit of the compound, which highlights that the Zr atom is six-coordinated by O atoms in an octahedral geometry. The Zr-O bond distances are in the range 2.038 (3)-2.095 (3) Å , with a mean value of 2.067 (3) Å , which is in good agreement with those found in other zirconium(IV) compounds, such as BaZr(PO 4 ) 2 (Bregiroux et al, 2009), Zr 2 (MoO 4 )(PO 4 ) 2 (Cetinkol et al, 2009) and Rb 2 Zr(IO 3 ) 6 (Shehee et al, 2005). The P and Al atoms are all tetrahedrally coordinated by O atoms.…”

Structures and properties of functional metal iodates

“…The Mo 6+ cation undergoes a C 2 distortion toward an edge, resulting in two short, two long and two normal MoO bonds. Rb 2 Mo(IO 3 ) 6 ( 3 R , CS) is isostructural with M 2 Zr (IO 3 ) 6 (M = Rb + , Cs + ) previously discussed, therefore its structure will not be discussed in detail here [61]. Unusually, the MoO 6 octahedron is undistorted with six equal MoO bonds.…”

“…They revealed very strong SHG responses of about 500 and 400 × -SiO 2 , respectively, and both are phase-matchable ( Figure 2) [48,49]. A 2 Ti(IO 3 ) 6 (A = K + , Rb + , Cs + , Tl + , Ag + ), BaTi(IO 3 ) 6 and A 2 Zr(IO 3 ) 6 (A = Rb + , Cs + ) are isostructural and crystallize in the centrosymmetric (CS) space group 3, R hence they are not SHG-active [49,[60][61][62]. These compounds mentioned above are topologically similar and exhibit a zero-dimensional (0D) [Ti(IO 3 ) 6 ] 2 or [Zr(IO 3 ) 6 ] 2 anionic unit consisting of a non-distorted d 0 -TM cation linked to six IO 3 anions.…”

Recent advances on second-order NLO materials based on metal iodates

“…The Mo 6+ cation undergoes a C 2 distortion toward an edge, resulting in two short, two long and two normal Mo O bonds. Rb 2 Mo(IO 3 ) 6 (R3 CS) is isostructural with M 2 Zr(IO 3 ) 6 (M = Rb + , Cs + ) previously discussed [92]. and their structures feature a three-dimensional (3D) network in which the 1D chains of corner-sharing MoO 6 octahedra are further bridged by iodate groups, with the Rb + or Cs + cations filling the void space to balance the charge (Fig.…”

“…). Rb + , Cs + ) are isostructural and crystallize in the CS space group (R3), and they are not SHG-active[90][91][92][93]. These compounds mentioned above are topologically similar and exhibit a zero-dimensional (0D) [Ti(IO 3 ) 6 ] 2− or [Zr(IO 3 ) 6 ] 2− anionic unit consisting of a nondistorted TiO 6 or ZrO 6 octahedron linked with six IO 3 groups.…”
