AbstractThe syntheses, crystal structures and magnetic properties are described for two novel 2D heterometallic Cu-II-Sr-II coordination polymers {Sr(H2O)(6)[(Im)(4)Cu-4(pdc)(4)Sr(H2O)(4)]center dot 6H(2)O}(n) (1) and [Cu-2(H2O)(2)(pdc)(2)Sr(H2O)(3)](n) (2) (H(3)pdc = 3,5-pyrazoledicarboxylic acid; Im = imidazole). The 1 : 1 : 1 : 5 reaction of SrCl2 center dot 6H(2)O, Cu(NO3)(2)center dot 3H(2)O, H(3)pdc and imidazole in H2O-EtOH at 120 degrees C under autogenous pressure gave 1. Complex 2 was obtained from the 1 : 1 : 1 H(3)pdc/Sr(OH)(2)center dot 8H(2)O/Cu(NO3)(2)center dot 3H(2)O reaction mixture in H2O-EtOH under solvothermal conditions. Complex 1 can be described as a 2D grid-shaped network with the four Cu-II ions in a saddle-like conformation. In complex 2, Sr-II ions link metalloligands [Cu-2(pdc)(2)(H2O)(2)](2-) to generate a 2D layer framework. Variable-temperature solid-state dc magnetic susceptibility studies have been performed in the temperature range 2.0-300 K for complexes 1 and 2. Antiferromagnetic Cu-II ... Cu-II exchange interactions were found for both 1 and 2.
