چکیده
In the title Schiff base, C(18)H(14)N(4)O, the amido -NH- unit is connected to one of the two pyridyl N atoms at an N(-H)⋯N distance of 2.624 (2) Å. The mol-ecular packing features an inter-molecular C-H⋯N R(2) (2)(6) hydrogen-bonding ring motif.

In the title complex, [Co(NCS)(2)(C(13)H(11)N(3)O)(2)], the Co(II) centre adopts a distorted octa-hedral coordination geometry with two cis-bidentate Schiff base ligands and two cis thio-cyanate ligands. The Schiff base ligand coordinates via the imine N and pyridine N atoms. The Co(II) atom lies on a crystallographic twofold rotational axis. Non-classical inter-molecular C-H⋯O hydrogen bonds l...

There are three different Mn(II) complexes in the asymmetric unit of the title compound, [Mn(C(15)H(16)N(4))(H(2)O)(2)]Br(2)·2{[MnBr(C(15)H(16)N(4))(H(2)O)]Br}·[MnBr(2)(C(15)H(16)N(4))]. In the neutral complex, the Mn(2+) ion is six-coordinated in a distorted octa-hedral environment by four N atoms of the tetra-dentate ligand N,N'-bis-(2-pyridylmethyl-ene)propane-1,3-diamine (bppd) and two brom...

In the title mononuclear Cd(II) complex, [CdCl(2)(C(11)H(17)N(3))], the Cd(II) atom is coordinated by two Cl atoms and three N atoms from the tridentate Schiff base ligand in a distorted square-pyramidal environment. The three N atoms and one Cl atom constitute the base of the pyramid, whereas the other Cl atom occupies the apical position.

The asymmetric unit of the title compound, C(14)H(11)ClN(2)O, contains two independent mol-ecules. In one mol-ecule, the two aromatic rings form a dihedral angle of 45.94 (16)°, while in the second mol-ecule this angle is 58.48 (16)°. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into two crystallographically independent sets of chains propagating along [001].
