Isomorphous tetrazolate MnII and CoII compounds built on Δ-chain showing different magnetic behaviors

Abstract

As a continuation of the study on using the tetrazolate ligands to construct coordination polymers, two isomorphous 3D coordination polymers built on Δ-chain topological rod-shaped SBUs have been synthesized with formulae [M23-OH)L1L2]n (5-amino-1H-tetrazole (HL1), 2,3-pyrazinedicarboxylic acid (H2L2) and different 3d spin carriers (M = MnII, 1 and CoII, 2)). The SBU consists of corner-sharing [M33-OH)] isosceles triangle motifs with mixed multiple (μ4-tetrazolyl, μ3-OH, syn-syn carboxylate) bridges. The SBUs were further linked by syn-anti carboxylates to form the sra net. Spin-competing was observed in the MnII compound, whereas the CoII compound exhibits spin-canting.
