In the title complex, [ZnBr(2)(C(12)H(9)FN(2))], the Zn(II) atom has a distorted tetra-hedral Br(2)N(2) coordination sphere. The organic ligand is bidentate, coordinating the Zn(II) atom via two imine N atoms. The benzene and pyridine rings are oriented at a dihedral angle of 10.49 (1)°. In the crystal, weak C-H⋯F and C-H⋯Br hydrogen bonds are observed.
In the crystal structure of the title compound, [Co(C(13)H(9)N(2)O)(2)]·2C(3)H(7)NO, the Co(II) ion is four-coordinated by two N atoms and two O atoms from two deprotonated 2-(1H-benzimidazol-2-yl)phenol ligands in a distorted tetra-hedral geometry. The dimethyl-formamide solvent mol-ecules are found inside a two-dimensional network structure formed by inter-molecular N-H⋯O hydrogen bonds linki...
In the title salt, (C(16)H(36)N)[Fe(C(3)H(9)OSi)(4)], the cation contains a central N atom bonded to four n-butyl alkyl groups in a tetra-hedral arrangement, while the anion contains a central Fe(III) atom tetra-hedrally coordinated by four trimethyl-silanolate ligands.
The title compound, C(24)H(30)N(2)P(2)S(2), was obtained by the reaction of Ph(2)PN(iPr)P(Ph)N(iPr)H with elemental sulfur in tetra-hydro-furan. In the solid state, intra-molecular N-H⋯S hydrogen bonding influences the mol-ecular conformation; a P-N-P-N torsion angle of 2.28 (9)° is observed. The two phenyl rings attached to one P atom form a dihedral angle of 74.02 (4)°.
In the title complex, [CuCl(2)(C(14)H(14)N(2))], the Cu(II) atom exhibits a very distorted tetra-hedral coordination geometry involving two chloride ions and two N-atom donors from the Schiff base ligand. The range for the six bond angles about the Cu(2+) cation is 81.49 (11)-145.95 (9)°. The chelate ring including the Cu(II) atom is approximately planar, with a maximum deviation of 0.039 (4) Å...
In the structure of the title compound, [CoCl(2)(C(9)H(16)N(2)Si)(2)], the Co(II) atom is located on an inversion center in a slightly distorted tetra-hedral environment formed by two chloride ions and the pyridine N atoms of two chelating 6-methyl-2-[(trimethyl-silyl)amino]pyridine ligands. The dihedral angle between the planes of the pyridine rings is 80.06 (5)°. Cohesion within the crystal s...
In the title compound, C(14)H(15)NO(3)S, the geometry around the S atom of the SO(2) group is distorted tetra-hedral. The meth-oxy- and methyl-substituted aromatic rings are oriented at a dihedral angle of 71.39 (9)°. Inter-molecular N-H⋯O hydrogen bonds form inversion dimers, which stabilize the crystal structure.
Cerium(III) nitride chloride, Ce(2)NCl(3), contains trans-edge connected [NCe(4)](9+) tetra-hedra (222 symmetry) forming chains parallel to the c axis that are separated by Cl(-) anions. The Ce(3+) cations (..m symmetry) are each surrounded by two N(3-) and six Cl(-) anions in a bicapped trigonal prismatic coordination geometry (CN = 8).
In the title compound, C(9)H(12)BrNO(3)S, the two tetra-hydro-furan rings adopt envelope conformations, the pyrrolidine ring adopts a half-chair conformation and the six-membered ring is in a boat conformation. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into R(2) (2)(8) and R(2) (2)(14) rings along the b-axis direction.
