In the title compound, [Ni(NO(3))(2)(C(6)H(15)OP)(2)], the Ni(II) ion, lying on a crystallographic twofold axis, adopts a distorted octa-hedral coordination, consisting of O-donor atoms of two symmetry-related triethyl-phospine oxide and two bidentate nitrate ligands.

In the title mononuclear nickel(II) complex, [Ni(C(20)H(20)N(2)O(2))], the Ni atom is four-coordinated in a square-planar geometry by the four donor atoms of the Schiff base ligand. The dihedral angle between the two benzene rings is 9.4 (2)°. The cyclo-hexyl group adopts a C-form chair conformation.

The title compound, [Ni(C11H16O2PS2)2], contains a four-coordinate Ni(II) cation with an idealized square-planar geometry. The metal atom is surrounded by two chelating isobidentate dithio-phospho-nate ligands in a trans or anti configuration, binding through the S-donor atoms.

The title dihaloaniline, C(6)H(5)ClIN, shows no significant hydrogen bonds nor the commonly observed I⋯I inter-actions in the crystal structure, although an amino group and an I atom are available for such contacts. The crystal structure is stabilized by weak inter-actions involving the amine functionality as donor group and N or halogen atoms as acceptors.

Nitrogen-bridged donor-acceptor multifused dithienopyrrolobenzothiadiazole (DTPBT) and dibenzothiadiazolopyrrolothiophene (DBTPT) were successfully synthesized by intramolecular Cadogan annulation. The electron-deficient benzothiadiazole unit in DTPBT can be converted to benzoselenadiazole and quinoxaline moieties through reduction/cyclization to generate dithienopyrrolobenzoselenadiazole (DTPB...

In the context of our systematic investigations of pentaand hexacoordinate silicon compounds, which included dianionic tri(O,N,O1; O,N,N1) and tetradentate (O,N,N,O; O,N,N1,O1) chelators, we have now explored silicon coordination chemistry with a dianionic tetradentate (N,N1,N1,N) chelator. The ligand [o-phenylene-bis(pyrrole-2-carbaldimine), H2L] was obtained by condensation of o-phenylenediam...

The title compound, [Hg3(C6F4)3]·C6N4, contains one mol-ecule of tetra-cyano-ethyl-ene B per one mol-ecule of mercury macrocycle A, i.e., A•B, and crystallizes in the monoclinic space group C2/c. Macrocycle A and mol-ecule B both occupy special positions on a twofold rotation axis and the inversion centre, respectively. The supra-molecular unit [A•B] is built by the simultaneous coordination of...

The impact of four typical adsorbates, namely H2O, H+, Cl−, and OH−, on three different planes, namely, Fe(110), Cr(110) and Cr-doped Fe(110), was investigated by using a density functional theory (DFT)-based model. It is verified by the adsorption mechanism of the abovementioned four adsorbates that the Cr-doped Fe(110) plane is the most stable facet out of the three. As confirmed by the adsor...

By changing the N-donor groups of benzonitrile-based reactants, three novel isopolymolybdate-based compounds, [Cu(DBIBA)3][δ-HMo8O26] (1), [Cu(H2O)(DIBA)(DIBAH)(γ-HMo8O26)]·2H2O (2), and [CuI(DTBA)(Mo2O6)] (3) (HDBIBA = 3,5-di(benzoimidazol-1-yl)benzoic acid, HDIBA = 3,5-di(1H-imidazol-1-yl)benzoic acid and HDTBA = 3,5-di(1,2,4-triazol-1-yl)benzoic acid) were synthesized, in which the benzene c...

In the title heteronuclear Ni(II)-Ho(III) complex (systematic name: {μ-6,6'-dieth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato-1κ(4)O(1),O(1'),O(6),O(6'):2κ(4)O(1),N,N',O(1')}trinitrato-1κ(6)O,O'-holmium(III)nickel(II)), [HoNi(C(20)H(22)N(2)O(4))(NO(3))(3)], with the hexa-dentate Schiff base compartmental ligand N,N'-bis-(3-ethoxy-salicyl-idene)ethyl-enediamine (H(2)L), the Ho...
