This material was prepared using a new tetracyano-substituted quinoidal organic small molecule 7 based on a tricyclic heterocycle 4-hexyl-4H-pyrrolo[2,3-d:5,4-d']bis(thiazole) (C6-PBTz). Single crystal X-ray diffraction of the 2,6-diiodo derivative of the parent C6-PBTz, showed a disordered hexyl chain and a nearly linear arrangement of the substituents in positions 2 and 6 of the tricyclRSC advancesMagnetic ordering in a vanadium-organic coordination polymer using a pyrrolo[2,3-d:5,4-d']bis(thiazole)-based ligand.PMC9088712MRI Program CHE-1726652IIA-130134614204511523611Risko CNesterov VNGetmanenko YAMullins CSLake SJohnston-Halperin EfalseMagnetic ordering in a vanadium-organic coordination polymer using a pyrrolo[2,3-d:5,4-d']bis(thiazole)-based ligand.Here we present the synthesis and characterization of a hybrid vanadium-organic coordination polymer with robust magnetic order, a Curie temperature T C of ∼110 K, a coercive field of ∼5 Oe at 5 K, and a maximum mass magnetization of about half that of the benchmark ferrimagnetic vanadium(tetracyanoethylene)∼2 (V·(TCNE)∼2).
