Abstract

New ternary and quaternary transition-metal chalcogenides have resulted from substitutional chemistry of known phases. Ta/sub 2/Ni/sub 3/S/sub 8/ and Ta/sub 2/Pt/sub 3/Se/sub 8/ have been synthesized and characterized by single-crystal X-ray techniques. These compounds adopt the Nb/sub 2/Pd/sub 3/Se/sub 8/ structural type. Hence in Ta/sub 2/Ni/sub 3/S/sub 8/ Ni occupies both square-planar and square-pyramidal sites as similarly does Pt in Ta/sub 2/Pt/sub 3/Se/sub 8/. The electrical conductivity of Ta/sub 2/Ni/sub 3/S/sub 8/ establishes its semiconducting behavior. Ta has been substituted for Nb in the Nb/sub 2/Pd/sub 0.71/Se/sub 5/ type to yield Ta/sub 2/Pd/sub 0.89/S/sub 5/ which has been characterized by single crystal X-ray techniques. The square-planar Pd sites in the van der Waals' gap of this layer structure are 78.6(4)% occupied. This compound shows metallic behavior. The compound Co/sub 2/Nb/sub 4/PdSe/sub 12/ has been synthesized and characterized by single-crystal X-ray techniques. It is of the Co/sub 2/Ta/sub 4/PdSe/sub 12/ structural type and thus contains Nb in both trigonal prismatic and octahedral sites.

Cs{sub 2}PdSe{sub 8}(1), a novel palladium polyselenide with a three-dimensional open framework structure, has been synthesized via a solvothermal reaction using ethylenediamine as solvent. Its crystal structure has been determined by single crystal X-ray diffraction. The structure belongs to the tetragonal space group I4{sub 1}/acd (No. 142), a = 14.935(2), c = 12.907(3) {angstrom}, V = 2897.0(8) {angstrom}{sup 3}, Z = 8, R{sub 1} = 0.044, and wR{sub 2} = 0.063, for 640 unique reflections.

Journal Article Liang, C S ; Eddy, M M ; Gier, T E ; ... - Chemistry of Materials; (United States)

The syntheses, structures, and physical properties of several members of a new family of noncentrosymmetric, open-framework, ion-exchangeable phases which have a substantial nonlinear optical response (Nd:YAG 1064 nm) are described. Single-crystal (to 2 mm) hydrothermal synthesis of Na[sub 1/2](H[sub 3]O)[sub 1/2]Nb[sub 2]PO[sub 8] was carried out at 30,000-40,000 psi and 650-700[degrees]C. The structure of Na[sub 1/2](H[sub 3]O)[sub 1/2]Nb[sub 2]PO[sub 8], as determined from single-crystal X-ray data consists of an octahedral (NbO[sub 6])/tetrahedral (PO[sub 4]) framework, connected via Nb-O-P and Nb-O-Nb bonds, with cavities and channels occupied by the Na[sup +] and H[sub 3]O[sup +] cations.
