Resumen:
The newly obtained complexes [NiII8LnIII6(Piv)16(teaH)6(OCH3)2(CO3)2(H2O)2] Ln=Gd, Dy, show a remarkable 5-carbonate bridged octanuclear planar {Ni4Ln4} core further capped with embedded {Ni3Ln} cubane motifs to afford a rod shape nano-sized molecule of about 1.2 x 2.8 nm. Unusual MCE behaviour has been found due to multiple low lying excited sates arising from competing ferromagnetic and anti-ferromagnetic Ni-Ni and Ni-Ln exchange interactions.
