摘要: Two new infinite coordination chain compounds [Gd(CH3CO2)3(dmf)]∞ (1) and {[Gd(HO(CH2)3CO2)3(H2O)]·H2O}∞ (2) have been obtained attempting to modify a prototype molecular cooler. The structures of both as determined by single-crystal X-ray diffraction are reported, together with detailed study their magnetic thermal properties, describing for large magneto-caloric effect. dominant ferromagnetic interaction present in 2 clearly favours this material at low applied fields, respect 1 that exhibits antiferromagnetic interactions. Magneto-structural correlations the sign strength interactions derived carboxylato-bridged Gd(III) systems.
