Abstract

Abstract:

The organic-inorganic hybrid complex with formula [(CuL)₂Cu₃(μ-1,1-N₃)₄(ClO₄)₂], complex 1, {CuL, [5,6:14,15-dibenzo-1,4,8,12-tetraazacyclopentadeca-7,13-diene-2,3-dione(2-)]copper(II)}, has been synthesized and structurally determined. The crystals of complex 1 crystallize in the triclinic system with space group P1, a=0.92983(12) nm, b=1.09644(14) nm, c=1.27396(16) nm, α=70.782(2)°, β=86.266(2)°, γ=78.284(2)°. In this complex, the five copper ions are bridged by macrocyclic oxamide groups and azido. Furthermore, C―H···O hydrogen bond interactions link the pentanuclear fragments to form a 2D supramolecular architecture.

Key words: Macrocyclic oxamide complex; Azido complex; Polynuclear complex
