El pdf del artículo es la versión post-print.-- et al.The use of triethanolamine (teaH 3) in 3d/4f chemistry produces the enneanuclear cluster compound [Cu II 5Gd III 4O 2(OMe) 4(teaH) 4(O 2CC(CH 3) 3) 2(NO 3) 4]·2MeOH·2Et 2O (1·2MeOH·2Et 2O) whose molecular structure comprises a series of vertex- and face-sharing {Gd IIICu II 3} tetrahedra. Magnetic studies reveal a large number of spin states populated even at the lowest temperatures investigated. Combined with the high magnetic isotropy, this enables 1 to be an excellent magnetic refrigerant for low temperature applications. © The Royal Society of Chemistry 2011.This work was supported by an ARC Discovery grant (KSM), the Spanish MICINN (contracts MAT2009-13977-C03 and CSD2007-00010); the EPSRC, Leverhulme Trust and the Royal Society of Chemistry (EKB).Peer Reviewe
