A 3D Cu(II) Tetrazolate Coordination Polymer Based on Pentanuclear Units with Large Coercive Field

Abstract

A novel 3D coordination polymer {[Cu4.5 (BTZE)1.5 (μ3-OH)3(μ-OH)(SO4)(H2O)1.5·4H2O]}n (1) was synthesized by a solvothermal reaction of 1,2-bis(tetrazol-5-yl) ethane (BTZE) with copper sulfate. Compound (1) contained triangular [Cu3(μ3-OH)] clusters magnetic Δ-chains linked with in situ generated μ2-BTZE ligands to form a 2D cyclic annular layer. This 2D layer structure was further modified with sulfate and symmetry-related μ3-OH groups, extending to a 3D coordination framework structure. The magnetic performance of (1) was characterized in a temperature range of 2-300 K in terms of direct-current and alternating-current magnetic susceptibilities, revealing that (1) was canted ferromagnet with a critical temperature (Tc) of 9.5 K. Notably, (1) behaved as a hard magnet with the coercive field of 2.3 kOe at 2 K, showing significant unique characteristics compared to the reported spin canting systems based on pure Cu(II) ions.
