| Abstract: | Three new nickel(II) complexes constructed with N‐(2‐hydroxybenzyl)‐β‐alanine (H2L), namely NiL(phen)H2O]·H2O ( 1 ) (phen = 1.10‐phenanthroline), Ni4L4(H2O)4]·5H2O ( 2 ) and KNi4L4(NCS)(H2O)5]·5.42H2O ( 3 ) have been synthesized and characterized by single‐crystal X‐ray diffraction analysis. Complex 1 exhibits a discrete structure, and the structures are bound together through hydrogen bonding to a one‐dimensional chain in ladder‐like fashion. Complexes 2 and 3 contain similar Ni4(μ2‐O)6] cores with “zig‐zig” arrangement. In complex 3 , the tetranuclear nickel units Ni4L4(H2O)4] and Ni4L4(NCS)(H2O)] are alternately bridged by potassium atoms to a one‐dimensional chain. The neighboring chains are further linked up by {K2O2} units to a two‐dimensional layer structure. Moreover, the IR, XRD, TGA and the temperature‐dependent magnetic susceptibility for 2 and 3 have also been studied. |
