The title complex, [Os3(C2H4N)H(CO)10] or [Os3(CO)10(μ-H)(μ-HN=C—CH3-1κN:2κC)], was synthesized in 41.6% yield by reactions between Os3(CO)11(CH3CN) and 2,4,6-trimethylhexahydro-1,3,5-triazine. The central osmium triangle has two OsI atoms bridged by a hydride ligand and a μ-HN= C—CH3-1κN:2κC triazine fragment. Three CO ligands complete the coordination sphere around each OsI atom, while the remaining Os0 atom has four CO ligands. Each Os atom exhibits a pseudo-octahedral coordination environment, discounting the bridging Os—Os bond.

The polymeric structure of the title complex, [Cu(C7H4ClO3)2(C6H7NO)2] n , at 100 (2) K contains two-dimensional sheets parallel to the ac plane. The CuII atom, lying on an inversion centre, has an octahedral coordination environment. It is bonded in a trans-square-planar arrangement to the N atoms of two 3-pyridylmethanol molecules and one carboxylate O atom from each of two 4-chlorosalicylate anions. The axial positions are also occupied by 3-pyridylmethanol, but coordinated through O rather than the pyridyl N atom.

In the title complex, [NiCl2(C5H5N)(C24H16N6)], the NiII ion is six-coordinated in a distorted octahedral coordination environment defined by three N atoms of the tridentate 2,3,5,6-tetra-2-pyridylpyrazine ligand, one N atom of the pyridine ligand and two Cl− anions, with the latter being mutually trans. The complex is disposed about a twofold rotation axis along the a axis. The complex molecules are connected in the crystal via C—H...Cl, C—H...N and π–π [closest inter-centroid separation = 3.7446 (14) Å between pyridyl rings].

The Mean

In the mononuclear title complex, [Co(N3)2(C12H8N4S)2], the cobalt(II) atom is located on an inversion centre and displays an axially weakly compressed octahedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis(pyridin-2-yl)-1,3,4-thiadiazole ligands, whereas the axial positions are occupied by N atoms of the azide anions. The thiadiazole and pyridine rings linked to the metal are almost coplanar, with a maximum deviation from the mean plane of 0.0273 (16) Å. The cohesion of the crystal is ensured by weak C—H...N hydrogen bonds and by π–π interactions between pyridine rings [intercentroid distance = 3.6356 (11) Å], forming a layered arrangement parallel to (001). The structure of the title compound is isotypic with that of the analogous nickel(II) complex [Laachiret al.(2013).Acta Cryst.E69, m351–m352].

Distorted Octahedral Coordination Environment

The title compound, [Co(C18H37N2)2(NCS)4], consists of a cobalt(II) ion positioned on the origin of the triclinic unit cell. It is coordinated by the N atoms of two trans-oriented 1-dodecyl-4-aza-1-azoniabicyclo[2.2.2]octane (DABCO+) cations, which carry n-dodecyl chains at the non-coordinating N atoms. The distorted octahedral coordination environment of the CoII ion is completed through four N atoms of isothiocyanate ions, which are arranged within the equatorial plane. Non-classical hydrogen bonding of the types C—H...N and C—H...S between the filamentous molecules lead to the formation of layers parallel to (001).

The binuclear title complex, di-μ-iodido-bis({2-[(benzylamino-κN)methyl]phenyl-κC1}palladium(II)), [Pd2I2(C14H14N)2], was prepared by reaction of [Pd{C6H4(CH2NHCH2Ph)-2}(μ-OAc)]2with NaI. It crystallizes with one discrete molecule in the asymmetric unit. The molecule presents an iodide-bridged dimeric structure with acisoidarrangement with respect to theC,N-cyclopalladated ligands. Both PdIIatoms have a slightly distorted square-planar coordination environment. Weak intermolecular contacts of the type C—H...Pd seem to have a significant influence on the arrangement of the molecules along thebaxis in the crystal.
