A new ruthenium (III) Schiff base complexes of the type [RuX2 (PPh3)2(L)] (where X = Cl or Br; L = monobasic bidentate Ligand) have been synthesized. All the complexes were characterized by analytical, IR, electronic and EPR spectral studies. An octahedral geometry has been tentatively proposed to all the new complexes. Further the ligands and complexes were subjected to antimicrobial activity ...

The benzene-o-dithiol/pyridylimine (S-S)/(N-N) ligand H2-7, representing the first example of a new type of bis(bidentate) heterodonor ligands with a mixed donor set, has been synthesized by Schiff base condensation of pyridine-2-carbaldehyde with an amine-substituted benzene-o-dithiol moiety. Bis(cyclopentadienyl)titanium dichloride reacts selectively at the S-S donor group of H2-7 to yield co...

Two acyclic Schiff-base ligands, bis-5,5′-(1,3-propanediyldiimino)-2,2-dimethyl-4-hexene-3-one and bis-5,5′-(1,3-ethanediyldiimino)-2,2-dimethyl-4-hexene-3-one, were used to complex homoleptic triethylaluminum and tris[bis(trimethylsilyl)amino]alu minum, respectively. The acid–base reactions proceeded in excellent yields with elimination of ethane or bis(trimethylsilyl)amine during in situ depr...

In the title mononuclear Zn(II) complex, [Zn(C(13)H(19)N(2)O(2))(2)]·2H(2)O, the Zn(II) atom is coordinated by two O atoms and three N atoms from two crystallographically different Schiff base ligands in a distorted trigonal-bipyramidal environment. One O and two N atoms constitute the base of the pyramid, and one O and one N atoms occupy the apical positions. Inter-molecular O-H⋯O and O-H⋯N hy...
