  The reaction of hydroxy-rich Schiff bases [H(3)L = XC(6)H(3)(OH) CH=NC(R)(CH2OH)(2) where X = H, 5-CI or 5-Br and R = Me or Et] with [MoO2(acac)(2)] (acac = acetylacetonate) gave mononuclear complexes [MoO2(HL)(MeOH)]. The complexes were characterised by spectroscopic methods and by a single-crystal structure determination. Reaction of the mononuclear complexes with Ph(2)PCH(2)PPh(2) in methanol or acetonitrile led to five-co-ordinate polymeric compounds of the type [MoO(L)](n) in which the fifth position of the distorted square pyramid is occupied by the oxygen atom of a CH2O- moiety of a neighbouring repeat unit. The complex [MoO2(HL(3))(MeOH)][H(3)L(3)=2-(5-chlorosalicylideneamino)-1 ,3-dihydroxy-2-methylpropane] reacted with Cu(O(2)CMe)(2) in methanol-acetonitrile to yield the mixed-metal cluster [Cu(2)Mo(2)O(4)L(2)(3)(OMe)(2)] with a Cu2Mo2O4 cubane-like core. Reflux of this complex with an excess of 2,2'-bipyridine in acetonitrile yielded pale blue-green crystals of the tetranuclear cluster [CuMo3O8(HL(3))(2)(bipy)(2)] the structure of which has been determined by X-ray crystallography. The molybdenum part may be described in terms of three ore-bridged centres, one tetraoxomolybdate [MoO4](2-) and two six-co-ordinated MoO2(Schiff base) moieties. The magnetic properties of this compound have been studied in the temperature range 5-300 K.

  Reactions of Schiff base ligands, OH-C6H4-CH=NC(R)(CH2OH)(2) (R = CH3, H3L1; R = C2H5, H3L2; R = CH2OH, H3L3) with Mn(ClO4)(2)center dot 6H(2)O in MeOH solutions afforded Mn-4(III) complexes, i.e. compounds [Mn-4(L-1)(2) (HL1)(2)(H2O)(2)(MeOH)(2)](ClO4)(2)center dot yH(2)O (y = 1, 1a center dot H2O; y = 2, 1b center dot 2H(2)O), [Mn-4(L-2)(2)(HL2)(2)(MeOH)(4)](ClO4)(2) (2a), [Mn-4(L-2)(2)(HL2)(2)(H2O)(2)(MeOH)(2)] (ClO4)(2)center dot MeOH (2b center dot MeOH) and [Mn-4(L-3)(2)(HL3)(2)(H2O)(4)](ClO4)(2) (3). The crystal structures of 1a, 1b, 2a and 2b revealed the first examples of Mn-4(III) complexes consisting of three corner sharing [Mn-2(III)(mu-OR)(2)] units in trans orientation. The Schiff bases behave as chelating through their phenolato oxygen and imino nitrogen atoms as well as bridging ligands through their deprotonated alkoxo oxygen atoms. In each tetranuclear entity, there are two doubly deprotonated and two triply deprotonated Schiff base ligands which connect two and three metal ions, respectively. Magnetic susceptibility measurements for 2b indicate the interplay of ferromagnetic and antiferromagnetic interactions resulting in a diamagnetic ground state. (C) 2013 Elsevier Ltd.
