RESUMO
In the title mol-ecule, C(15)H(14)N(2)O(2), the dihedral angle between the benzene rings is 5.93â (17)°. In the crystal, inter-molecular N-Hâ¯O hydrogen bonds link the mol-ecules into chains propagating in [010].
RESUMO
The asymmetric unit of the title compound, C(15)H(13)BrN(2)O, contains two independent mol-ecules with different conformations; the two aromatic rings form dihedral angles of 32.4â (4) and 27.5â (4)° in the two mol-ecules. In the crystal structure, inter-molecular N-Hâ¯O hydrogen bonds link mol-ecules into chains propagating in [100].
RESUMO
In the crystal structure of the title complex, [Cd(NCS)(2)(C(7)H(5)ClN(4))(2)](n), the Cd(II) atom lies on a crystallographic inversion center and assumes a distorted octa-hedral geometry. The 2-chloro-6-(1H-1,2,4-triazol-1-yl)pyridine mol-ecule acts as a terminal ligand. The thio-cyanate ligands function as µ(1,3)-bridging units connecting adjacent Cd(II) atoms with a separation of 5.7525â (11)â Å, forming a one-dimensional chain along the a axis.
RESUMO
In the title complex, [Co(NCS)(2)(C(10)H(9)N(3)O)(2)(H(2)O)(2)], the Co(II) ion is located on a crystallographic twofold rotation axis and is in a slightly distorted octa-hedral CoN(4)O(2) coordination environment. The dihedral angle between the pyridine and pyrazine rings is 85.86â (10)°. In the crystal structure, inter-molecular O-Hâ¯N and O-Hâ¯S hydrogen bonds link complex mol-ecules into a three-dimensional network.
RESUMO
In the title complex, [ZnCl(2)(C(11)H(9)N(5))], the Zn(II) ion assumes a distorted trigonal-bipyramidal ZnN(3)Cl(2) coordination geometry [Zn-N = 2.1397â (16)-2.2117â (17)â Å, Zn-Cl = 2.2470â (6) and 2.2564â (6)â Å]. The crystal packing exhibits π-π stacking inter-actions between the 2,6-dipyrazol-1-ylpyridine ligands of neighbouring mol-ecules.
RESUMO
In the title crystal structure, [Cd(NCS)(NO(3))(C(11)H(9)N(5))](n), the unique Cd(II) ion is coordinated in a distorted penta-gonal-bipyramidal environment. The axial thio-cyanate ligands act in a µ(1,3)-bridging mode to connect symmetry-related Cd(II) ions into one-dimensional chains along [010]. In addition, there are inter-molecular C-Hâ¯O contacts between chains.
