摘      要:Single-molecule magnets(SMMs), which exhibit slow magnetic relaxation at low temperatures, attract extensive interests for their potential applications in the fields of high-density information storage, quantum computing and molecule spintronics1-3. The cobalt system is one of the most widely studied SMMs, as it not only has high ground state(S = 3/2), but also possesses high magnetic anisotropy4. Two cobalt complexes with similar structures were synthesized using quinoline-2-carboxylic acid(HL) as the ligand. Both complexes are six-coordinated in anti-triangular prism coordination geometries. There are one and four molecule units per cell for 1 and 2 with nearest Co-Co distances of 7.129 and 5.855 ?, respectively, which lead to their intermolecular interactions zj’ of-0.0018 cm-1 and-0.012 cm-1. Both complexes are field-induced single-ion magnets. Complex 1 shows single slow-relaxation under 1.5 k Oe DC field attributed to the spin reversal, while complex 2 shows double slow-relaxation resulting from intermolecular dipolar interaction and spin reversal, respectively.
