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...

In the title complex, [Cu(C(12)H(13)NO(5))(C(12)H(8)N(2))]·0.5H(2)O, the Cu(II) ion is five-coordinated by one N atom and two O atoms from a tridentate Schiff base ligand, derived from the condensation of l-threonine and o-vanillin, and two N atoms from a 1,10-phenanthroline ligand in a distorted square-pyramidal geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds form a one-dimensio...

Crystals of the title compound, [Mo(C(14)H(13)NO(2))O(2)(CH(4)O)], were obtained by recrystallization from methanol. The Mo(VI) atom is coordinated by two oxide O atoms and by two O atoms and one N atom of the tridentate 1-[(2-oxidoprop-yl)iminometh-yl]-2-naphtholate Schiff base ligand. The coordination sphere is completed by the O atom of a methanol mol-ecule, yielding a distorted octa-hedron....

In the crystal structure, adjacent mol-ecules are linked together via N-H⋯O and N-H⋯Cl hydr...

In the title compound, [MnCl(2)(C(13)H(19)N(3)O)], the Mn(II) ion is penta-coordinated in a distorted square-pyramidal geometry. The coordination environment is defined by the N,N',N''-tridentate Schiff base ligand and one Cl atom in the basal positions and one Cl atom in the apical position. In the crystal, inter-molecular C-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional netw...

We have investigated the coordination modes of NNS Schiff base, thioether ligands to manganese(I) carbonyls. The ligands contain ortho substituted pyridines (H, CH3, OCH3, fluorophenyl) and varying substituents (H, CH3) at the Schiff base linkage. In general, reaction of [Mn(CO)5Br] with a tridentate NNS ligand in CH2Cl2 affords species in which the thioether-S may be bound or unbound to the ma...

The present article includes the generation of aromatic Schiff base tethered organosilatranes via two step synthetic pathways starting from anthracene-10-carbaldehyde and 1H-indole-3-carbaldehyde. synthesis was achieved by employing condensation reaction followed transesterification methodology. prepared containing schiff based ligands were structurally authenticated using spectroscopic techniq...

The asymmetric unit of the title compound, [Cu(NCS)(2)(C(11)H(17)N(3))], consists of two crystallographically independent mol-ecules. In each mol-ecule, the Cu(II) ion is five-coordinated in a distorted square-pyramidal geometry wherein the basal plane is defined by the N,N',N"-tridentate Schiff base and one N-bound thio-cyanate ligand. The second N-donor thio-cyanate group, located at the apic...
