Magnetocaloric effect (MCE) is one of the most promising features of molecular-based magnetic materials. We reported three Gd-based magnetic refrigerant materials, namely, Gd-2(L)(NO3)(H2O)?CH3CN?H2O (1, H2L = (Z)-N-[(1E)-(2-hydroxy-3-methphenyl)methylidene]pyrazine-2-carbohydrazonic acid), {Gd-6(L)(6)(CO3)(2)(CH3OH)(2)(H2O)(3)Cl}Cl?4CH(3)CN (2), and Gd-8(L)(8)(CO3)(4)(H2O)(8)?2H(2)O (3). Complex 1 contains two Gd-III ions linked by two eta (2):eta (1):eta (1):eta (1):mu (2)-L2- ligands, which are seven-coordinated in a capped trigonal prism, and complex 2 possesses six Gd-III ions, contributing to a triangular prism configuration. For complex 3, eight Gd-III ions form a distorted cube arrangement. Moreover, the large values of magnetic entropy in the three complexes prove to be excellent candidates as cryogenic magnetic coolants.
