Crown ether-like octanuclear molybdenum(v) clusters for cation binding and gas adsorption

Abstract

Octanuclear polyoxomolybdenum-based porous materials of Na8[Mo8O8(μ2-O)8(μ2-OH)8(3-apz)4]2·26H2O (1, 3-Hapz = 3-aminopyrazole), K8[Mo8O8(μ2-O)8(μ2-OH)8(3-apz)4]2·7H2O (2) and (NH4)4[Mo8O8(μ2-O)8(μ2-OH)4(3-apz)8]·20.5H2O (3) have been successfully synthesized by hydrothermal method and fully characterized, respectively. X-ray structural analyses show...
