Synthesis, crystal structure, and magnetic investigations of FePb1−xBaxP2O7 (0≤x&lt;1)

Introduction transition metal with d 10 electrons and lone pair cations with large radius into phosphate systems are helpful to get new crystal structure configuration. Guided by the above method, the first lead cadmium phosphate, Pb 2 Cd 3 (PO 4 ) 2 (P 2 O 7 ), was synthesized. Pb 2 Cd 3 (PO 4 ) 2 (P 2 O 7 ) features a three-dimensional (3D) structure, in which Pb (1) 2 O 8 dimer and Pb(2)O 5 polyhedra are filled between the twodimensional (2D) layers, which are composed of unique [Cd 6 P 8 O 30 ] groups. In the Pb II M II PO (M II = without or divalent [a] Physical and

Ba1.09Pb0.91Be2(BO3)2F2 (BPBBF), a previously unreported lead-containing beryllium borate fluoride, has been successfully grown through a high-temperature flux method. Its structure is solved by single-crystal X-ray diffraction (SC-XRD), and it is optically characterized via infrared, Raman, UV–vis–IR transmission, and polarizing spectra as well. SC-XRD data suggests that it can be indexed by a trigonal unit cell (space group P m1) with lattice parameters a = 4.7478(6) Å, c = 8.3856(12) Å, Z = 1, and V = 163.70(5) Å. This material could be considered as a derivative of the Sr2Be2B2O7 (SBBO) structural motif. It consists of 2D [Be3B3O6F3]∞ layers in the crystallographic ab plane, with divalent Ba2+ or Pb2+ cations serving as spacers among the adjacent layers. Ba and Pb were found to adopt a disordered arrangement in the trigonal prismatic coordination within the BPBBF structural lattice, which is evidenced by both structural refinements against SC-XRD data and energy dispersive spectroscopy. The UV absorption edge (279.1 nm) and birefringence (Δn = 0.054@ 546.1 nm) of BPBBF are confirmed by UV–vis–IR transmission and polarizing spectra, respectively. The discovery of this previous unreported SBBO-type material, BPBBF, along with other reported analogues such as BaMBe2(BO3)2F2 (M = Ca, Mg, and Cd), provide a prodigious example for tuning the bandgap, birefringence, and short UV absorption edge via simple chemical substitution.
