Cs2Pd3(P2O7)2 and Cs2Pd3(As2O7)2: A 3D Palladium Phosphate with a Tunnel Structure and a 2D Palladium Arsenate Containing Strings of Palladium Atoms

Cs2Pd3(P2O7)2 (1) and Cs2Pd3(As2O7)2 (2) have been synthesized by molten flux reactions and characterized by single-crystal X-ray diffraction. The structure of 1 consists of discrete PdIIO4 squares which are linked by P2O 7 groups via corner-sharing to generate a 3D framework containing 12-ring channels in which Cs+ cations are located. Compound 2 adopts a 2D layer structure with the interlayer space filled with Cs+ cations. Within a layer there are PdO4 squares and As 2O7 groups fused together via corner-sharing. Adjacent layers are stacked such that strings of Pd atoms are formed. The PdO 4 squares show eclipsed and staggered stacks with alternate short and long Pd...Pd distances. The two compounds adopt considerably different structures although they have the same general formula: Cs2Pd 3(X2O7)2. Compound 2 is the first palladium arsenate reported. Crystal data for 1: orthorhombic, space group Cmc21 (No. 36), a = 7.6061(4) A, b = 14.2820(7) A, c = 14.1840(7) A, and Z = 4. Crystal data for 2: tetragonal, space group P4/n (No. 85), a = 16.251(1) A, c = 5.9681(5) A, and Z = 4.

CsTi2As3O12: A cesium titanium(IV) arsenate with an open framework structure

A new ternary titanium(IV) arsenate, CsTi2As3O12, has been synthesized by a flux method and structurally characterized by single-crystal X-ray diffraction. It crystallizes in the cubic space group Ia3d (No. 230) with a = 20.495(3) ?, V = 8609(2) ?3, Z = 32, and R = 0.0242. The framework consists of vertex-sharing TiO6 octahedra and AsO4 tetrahedra, enclosing large cavities in which the cesium atom sites are partially occupied. The cavities are interconnected to form 3-dimensional channels. The structure is considerably different from those of NASICON and langbeinite.
