Two 1-D chain-like complexes based on 1,4-bis(imidazol-1-yl)-butane and 4-methylbenzoate: Synthesis, structure and magnetic properties

Abstract

This paper reports two 1-D chain-like compounds, namely, Co(mb) 2 (bimb) 0.5 ( 1 ) and Ni(mb) 2 (bimb) 0.5 ( 2 ) (mb = 4-methylbenzoate and bimb = 1,4-bis(imidazol-1-yl)-butane), which have been obtained via hydrothermal reaction and characterized by single-crystal X-ray diffraction, IR and elemental analysis. The formations of 1 – 2 are based on the linkage between the paddle-wheel shaped secondary building block units (SBUs) through long-chain bimb ligands. Compound 1 exhibits ferrimagnetic-like behavior, while compound 2 undergoes an unusual field-induced metamagnetic phase transition. This paper reports two 1-D chain-like compounds which are based on the linkage between the paddle-wheel shaped secondary building block units (SBUs) through long-chain bimb ligands. Compound 1 exhibits ferrimagnetic-like behavior, while compound 2 undergoes an unusual field-induced metamagnetic phase transition. • This paper reports two 1D chain compounds based on bimb and 4-methylbenzoate. • Compound 1 exhibits ferrimagnetic-like behavior. • Compound 2 undergoes an unusual field-induced metamagnetic phase transition.
