Systematic Synthesis of a Metal Organic Framework Based on Triangular Cu₃(μ₃-OH) Secondary Building Units: From a 0-D Complex to a 1-D Chain and a 3-D Lattice

Abstract

Reactions of Cu(CF(3)SO(3))(2) and pyrazole in methanolic solutions in the presence of stoichiometric amounts of py, py/4,4'-bpy, or 4,4'-bpy have yielded two new complexes [Cu(3)(μ(3)-OH)(μ-pz)(3)(py)(3)](CF(3)SO(3))(2)·0.5H(2)O (1) and [{Cu(3)(μ(3)-OH)(μ-pz)(3)(py)(2)}(2)(μ-4,4'-bpy)](CF(3)SO(3))(4) (2), a one-dimensional coordination polymer, {[Cu(3)(μ(3)-OH)(μ-pz)(3)(py)(μ-4,4'-bpy)](CF(3)SO(3))(2)·0.5H(2)O}(n) (3), and a three-dimensional, eight-fold interpenetrated extended lattice, {[Cu(3)(μ(3)-OH)(μ-pz)(3)(μ-4,4'-bpy)(1.5)](CF(3)SO(3))(2)·1.5H(2)O}(n) (4).
