  Playing with different metalloligands [NiL] and Hg to [NiL] ratios to tune the nuclearity of Ni(II)–Hg(II) complexes: Formation of di-, tri-, hexa- and nona-nuclear Ni–Hg clusters

  摘要：

  Five new hetero-metallic nickel(II)-mercury(II) complexes, [(NiL1)HgCl2] (1), [(NiL1)(2)HgCl2] (3), [(NiL1)(2)-Hg(N-3)(2)] (4), ({(NiL2)(2)Hg(N-3)(mu(1.1)-N-3)}(2)] (5) and [{(NiL2)Hg-2(N-3)(mu(1.1)-N-3)HgCl2}(2)(Hg(N-3)(mu(1.1)-N-3))] (6) have been synthesized by reacting metalloligands [NiL1] or [NiL2] (where H2L1 is N,N'-bis(salicylidene)-1,2-ethylenediamine and H2L2 is N,N'-bis(salicylidene)-1,3-propanediamine) with HgX2 (X- = Cl- or N-3(-)) at different molar ratios. All five complexes have been characterised by X-ray single-crystal structural, elemental and spectroscopic analyses. In complex 1, the Hg(II) ion is coordinated to two phenoxido oxygen atoms of one [NiL1] moiety and two terminal chloride ions to form a NiHg dinuclear complex. In the trinuclear complexes 3 and 4, the central Hg(II) ion is coordinated by two terminal [NiL1] units through two phenoxido oxygens from each and two terminal chloride (in 3) or azide (in 4) ions. The centrosymmetric hexanuclear complex 5 consists of two trinuclear [(NiL2)(2)Hg(N-3)(mu(1.1)-N-3)] units, where the phenoxido bridges connect two terminal Ni(II) atoms of the trinuclear units. In these trinuclear units, one azido ligand adopts a mu(l),(1)-briding mode between Hg and Ni whereas the other one is terminal. In the nonanuclear complex 6, two tetranuclear [{(NiL2)(2)Hg(N-3)(mu(1).(1)-N-3))HgCl2] units are linked to a central Hg(II) positioned on a two fold axis, via chlorido, azido, and phenoxido bridges. The tetranuclear unit is formed by the addition of a HgCl2 molecule to a trinuclear [(NiL2)(2) Hg(N-3)(mu(1.1)-N-3)] unit, similar to that present in 5. Complex 5 shows weak ferromagnetic interactions (J = +2.1 cm(-1)) between the two octahedral Ni(II) ions through double phenoxido bridges with a Ni-O-Ni bond angle of 95.87(11)degrees.

  (L4), (4) have been prepared. The syntheses have been achieved by reacting equimolar amounts of nickel perchlorate, mercuric chloride and the respective tetradentate Schiff base ligand (H2L) in methanol medium. The complexes have been characterized by microanalytical, spectroscopic, single crystal X-ray diffraction and other physicochemical studies. Structural studies on 1–4 reveal the presence of a
