Description
Summary:The influence of the size of the β-diketonate ligand substituent on the structure and thermal properties of volatile Ni(II) complexes is determined. To this aim, a corresponding heptanedione-3.5 (Hhd) derivative is prepared. The structures of [Ni 3 (hd) 6 ] and its derivatives [Ni 4 (OMe) 4 (hd) 4 (MeOH) 4 ] and [Ni 3 (OH) (hd) 5 (H 2 O)] 2 are studied by XRD. The trinuclear complex is similar to its simplest β-diketonate analogue. Such a tetranuclear structure is typical for mixed-ligand alkoxy-β-diketonate divalent metal complexes, whereas the hexuclear structure is unique. Thermal properties of Ni(II) β-diketonates in the series L =  R C(O)CHC(O) R , R  = Me, Et, t Bu are compared by the thermogravimetry method.
