Two novel gadolinium(III) trans-2-butenoate dimeric compounds [Gd2(O2CCH=CHCH3)6(H2O)4]·2H2O (1) and [Gd2(O2CCH=CHCH3)6(phen)2]·2H2O (2) have been synthesized via hydrothermal routes. Compound 1 consists of two independent dimers in the unit cell, one is doubly bridged (η2:η1:μ2) and the other quadruply bridged (two η1:η1:μ2 and two η2:η1:μ2). Compound 2 is dimeric with a quadruply bridged core (two η1:η1:μ2 and two η2:η1:μ2). Magnetic measurements for 2 show that there is a weak antiferromagnetic intramolecular GdGd interaction.
