英文摘要	A series of isostructural lanthanide one-dimensional (1D) chain complexes, [Ln(INNO)(Bza)(2)(H2O)(2)] center dot (H2O) {INNO = isonicotinate N-oxide, Bza = benzoic acid; Nd(1), Eu(2), Gd(3), Tb(4), Dy(5), Er(6) and Y(7)}, have been successfully isolated by hydrothermal reactions utilizing two distinct carboxylates as co-ligands. Due to the similar steric hindrance of the two carboxylic ligands, the neighboring lanthanide ions are bridged simultaneously by their carboxyl groups from the opposite sides to form a 1D chain structure. The shape analysis of the eight-coordinated Dy analogue 5 highlights the coordination geometry of the distorted square antiprism (D-4d). The solid-state luminescence of 2 and 4 was characterized. The static magnetic analysis of the Gd analogue 3 is indicative of the dominant weak intrachain antiferromagnetic interactions via the carboxylic ligands. Dynamic magnetic measurements for 5 revealed clear slow magnetic relaxation behaviour typical for single-molecule magnets (SMMs). Compound 5 represents a very rare example, reported as a mixed carboxylate bridged lanthanide SMM.; National Natural Science Foundation of China [21201061]; State Scholarship Fund of China [201308420653]; Scientific Research Foundation of Education Commission of Hubei Province [Q20111008]; SCI(E); ARTICLE; 41; 14114-14121; 46
