Abstract:
Two 3D supramolecular isomers with composition Co 2 (BDC) 2 (BPNO) (BPNO = 4,4′‐bipyridyl N , N′ ‐dioxide, BDC = 1,4‐benzenedicarboxylic acid) were prepared by using mixed ligands in different solvents. The two compounds are built up from different infinite chains of corner‐sharing CoO 6 octahedra. In compound 1 , 2D Co–BDC layers are pillared by neutral BPNO to form a 3D framework, while in compound 2 , the interconnection between the zig‐zag Co–O chains and two organic moieties leads to a Co‐based MIL‐53 analogue containing 1D nanosized rhombic channels. Compound 1 is a weak ferromagnet with two field‐induced magnetic transitions, and compound 2 displays antiferromagnetic interactions. Furthermore, compound 1 shows a typical solvatomagnetic effect and its desolvated compound appears to be a hidden weak ferromagnet with two field‐induced magnetic transitions. The structural variation between compounds 1 and 2 is ascribed to the different host–guest interactions within the two compounds and is believed to be responsible for the difference in the magnetic properties. As a result of their identical framework composition, compounds 1 and 2 , after removal of the guest molecules, exhibited similar gas adsorption behavior.
