A unique 3-D (3,18)-connected coordination framework based on a new type of {Zn18} double-stranded metallacrown†
Abstract
Hydrothermal reaction of ZnII salt with cyanuric acid (H3CA) and 1,2,4-triazole (Htz) yields a unique coordination polymer [Zn9(CA)2(μ3-tz)3(μ2-OH)6(μ3-OH)3]n (1), which displays a 3-D (3,18)-connected topological network based on a new type of {Zn18} double-stranded metallacrown.
