Abstract

The complexes Ni6(MPDMA)12, [Ni6(MPDMAH)12]X12 X = (I, ClO4) and Pd2(MPDMA)2Cl2 (MPDMA = t-S(CH2)3N(CH3)2) have been prepared and characterized. An X-ray diffraction study shows that the structure of [Ni6(MPDMAH)12] (ClO4)12 consists of a cyclic hexanuclear array of nickel atoms linked by sulphur bridging ligands. Infrared and electronic spectra show that there is no chelation in any of the nickel complexes. However, coordination through the nitrogen atoms occurs in the palladium complex. This behaviour differs from that of the homologous β-mercaptoamine, which forms monomeric chelate complexes with both nickel and palladium.

    Nickel(II) thiolates [Ni(μ2-SR)2]n occasionally construct cyclic structures by forming shared edges of the square NiS4 coordination planes, and several hexanuclear ring clusters [Ni(μ2-SR)2]6 have been reported [2]. So far, several tiara-nickel thiolates have been synthesized and characterized, including cyclic tetranuclear, [3] pentanuclear, [4,5] octanuclear, [6] nona- and undenuclear complexes [7]. Zhang et al. reported a new synthetic route to cyclic nickel thiolate complexes with two different thiolate bridges, which resulted in the selective formation of [{Ni(μ2-SiPr)(μ2-mtet)}6] and [{Ni(μ2-StBu)(μ2-mtet)}10] (mtet=2-methylthioethanethiolate) [8].
