| 摘要 | Two new air-stable mononuclear pentacoordinate Co-II complexes [Co(bpip)(NCS)(2)] (1) and [Co(bpip)Br-2] (2), which are based on a NNN-pincer ligand 2,6-bis(imidazo[1,5-a]pyridin-3-yl)pyridine (abbreviated as bpip), were successfully synthesized and structurally characterized. Although two different halogen and pseudohalogen terminal ligands were employed, single-crystal X-ray crystallographic analyses revealed that the Co-II center of 1 and 2 adopts C-4v symmetry and displays the similar distorted square-pyramidal geometry. Magnetic studies showed that two compounds exhibit slow magnetic relaxation in the presence of an applied dc field, namely, they display the behavior of single-ion magnets (SIMs). The reported two complexes enrich the chemistry of cobalt(II) single-ion magnets (SIMs) with low coordination numbers and highlight the differences in the magnetic behaviors caused by the different terminal ligands. |
