abstract = {The coordination characteristics of a tridentate,
π-conjugated Schiff base (HL·SMe) combined with
4-(methylthio)benzoic acid (Hbza·SMe) were explored in
methanol solution. A two-step aerobic process involving the
precursor NiCl2·6H2O afforded the trinuclear coordination
compound
[NiII3(L·SMe)4(bza·SMe)(MeOH)2]Cl0.5(CH3O)0.5·5.5MeOH·H2O
(1), while the precursor Ni(ClO4)2·6H2O resulted in
[NiII3(L·SMe)4(bza·SMe)(MeOH)2](ClO4)0.75(CH3O)0.25·1.5MeOH·0.75H2O
(2); in both cases the thioether-containing ligands are key
to isolation of crystalline products. Their solvent-free
cationic motif [Ni3(L·SMe)4(bza·SMe)]+, supported by two
different types of monodeprotonated chelate ligands, has
been studied by electrospray ionization mass spectrometry. 1
and 2 crystallize in the triclinic space group and
monoclinic space group Cc, respectively, and feature a
hitherto not observed triangular metal-ligand skeleton that
is characterized by predominantly ferromagnetic exchange
coupling between Ni(II) ions. Proof-of-concept infrared
reflection–absorption spectroscopy measurements of 1
deposited on a gold substrate indicate that this
moisture-stable compound retains its main structural
features upon adsorption on the metal surface, which enables
subsequent studies of catalytic properties of 1 on a solid
support.},
