Abstract
Using dioxyacetic acid (H(2)oda), CoCl2 center dot 6H(2)O and LiOH, a three-dimensional (3D) heterometallic complex [CoLi2(oda)(2)](n) (1) containing 1D Co-O-Li chains has been isolated under hydrothermal conditions. 1 represents a 3D hybrid magnetic rigid framework. To the best of our knowledge, such a chain with the arrangement of Co-O-Li linkages based on carboxylic acid has been first reported. Further analysis reveals that cis-conformation of dioxyacetic acid greatly favor chelate coordination of lithium(I) centers. Magnetic measurements indicate that in the low temperature, complex 1 shows weak ferromagnetic interaction, indicative of spin-canting behavior. (C) 2013 Elsevier B.V. All rights reserved.
