Synthesis and structural characterisation of two novel GdIIIβ-diketonates [Gd43-OH)42-H2O)2(H2O)4(hfpd)8]·2C6H6·H2O 1 and [Gd(hfpd)3(Me2CO)(H2O)] 2(hfpd–H = 1,1,1,5,5,5-hexafluoropentane-2,4-dione)

Abstract
Two novel GdIII–hfpd complexes 1 and 2 have been synthesised from aqueous and non-aqueous media; the crystal structural studies reveal that 1 has a M4O6 bicapped cubane core with the metals having tricapped trigonal prismatic geometry, while 2 is a monomeric adduct with water and acetone in the coordination sphere, with the metal having square antiprismatic geometry.
