Abstract
Three one-dimensional molybdenum oxide/2,2‘-bipyridine species have been prepared by hydrothermal methods and structurally characterized. The reaction of MoO3, 2,2‘-bipyridine, and H2O in the mole ratio 1:0.68:680 at 160 °C for 120 h in a 23 mL Teflon-lined Parr acid digestion bomb produces colorless rods of [MoO3(2,2‘-bipy)] (1) mixed with colorless octahedra of [Mo3O9(2,2‘-bipy)2] (3). The structure of 1 consists of one-dimensional chains of corner-sharing distorted {MoO4N2} octahedra. [Mo2O6(2,2‘-bipy)] (2) was prepared from a mixture of Na2MoO4·2H2O, MoO3, 2,2‘-bipyridine, MnCl2·4H2O, and H2O in the mole ratio 1:1:2:1.9:263 and was isolated as colorless plates. In contrast to the structure of 1, compound 2 consists of a chain of alternating corner-sharing {MoO4N2} octahedra and {MoO4} tetrahedra. Compound 3 was isolated as colorless octahedra. The structure of 3 consists of a chain of corner-sharing {MoO4N2} octahedra and {MoO4} tetrahedra that alternate such that each {MoO4N2} octahedron corner-share...
