The title Schiff base complex, [V(C(13)H(10)N(3)O(2))O(2)], features a square-pyramidal coordination geometry defined by the O,N',O'-donors of the tridentate Schiff base ligand and two oxide O atoms; one oxide O atom occupies the apical position. In the crystal, pyridinium-oxide N-H⋯O hydrogen bonds lead to zigzag supra-molecular chains with a flattened topology along [101]. The investigated cr...

In the title complex, [Cu(C(10)H(11)N(2)O(3))(NO(3))]·H(2)O, prepared from the Schiff base N'-(3-meth-oxy-2-oxidobenzyl-idene)-acetohydrazide, the Cu(II) atom is coordinated by two O atoms and one N atom from the ligand and one O atom from a nitrate group in a distorted square-planar geometry. The Cu(II) atom has a weak inter-action with another O atom of the nitrate group. The two O atoms of t...

In the title compound, [ZnCl(2)(C(13)H(19)N(3)O)], the Schiff base ligand acts as an N,N',N''-tridentate chelating agent, making two five-membered rings with the Zn(II) ion. The metal atom is five-coordinated by the Schiff base ligand and two Cl atoms in a distorted square-pyramidal geometry. An intra-molecular C-H⋯Cl inter-action occurs. In the crystal, adjacent mol-ecules are linked together ...

In the centrosymmetric dinuclear copper(II) title complex, [Cu(2)Br(2)(C(12)H(17)N(2)O)(2)]·H(2)O, each Cu(II) ion is five coordinated in a square-pyramidal geometry by the N,N',O-tridentate Schiff base, one Br atom and the bridging O atom of the centrosymmetrically related Schiff base. In the crystal, the water mol-ecules link the complex mol-ecules into infinite chains along the b axis via O-...

In the title complex, [Cu(NCS)(2)(C(12)H(19)N(3))], the Cu(II) atom is five-coordinated in a square-pyramidal geometry defined by one pyridine N, one imine N, and one amine N atom of the tridentate Schiff base ligand and two N-bonded thio-cyanate ions (one of the latter occupying the apical site). The three bridging C atoms and the two terminal C atoms of the Schiff base are disordered over two...

In the title complex, [Cu(C(14)H(11)NO(4))(C(12)H(8)N(2))], the tridentate Schiff base ligand is derived from the condensation of 2-hydr-oxy-1-naphthaldehyde and l-serine. The Cu(II) atom is five-coordinated by one N atom and two O atoms from the Schiff base ligand and by two N atoms from a 1,10-phenanthroline ligand in a distorted square-pyramidal geometry. In the crystal structure, the combin...

The V(IV) atom in the title complex, [V(C(11)H(13)BrClN(2)O)(C(5)H(7)O(2))O], is six-coordinated by one phenolate O, one imino N and one amino N atom of the tridentate anionic Schiff base ligand, by one oxide O atom, and by two O atoms of an acetyl-acetonate anion, forming a distorted cis-VN(2)O(4) octa-hedral coordination geometry. The deviation of the V atom from the plane defined by the thre...

The Cu(II) atom of the title complex, [Cu(C(16)H(12)ClNO(3))(C(3)H(4)N(2))]·H(2)O, has a distorted square-planar coordination geometry formed by a tridentate Schiff base dianion and an imidazole ligand. The imidazole is nearly coplanar with the coordination plane, the dihedral angle between the planes being 3.73 (12)°. In the Schiff base ligand, the two benzene rings are oriented at a dihedral ...

In the title dinuclear compound, [V(2)(C(15)H(17)N(2)O)(2)O(4)], each V(V) atom is six-coordinated by one oxide group, and by two N and one O atom of the tridentate Schiff base ligand, and bridged by two additional oxide O atoms, resulting in a centrosymmetric dimer. The metal centre has a distorted octa-hedral coordination with the monoanionic Schiff base ligand occupying one equatorial and tw...
