Homo-metallic metal alkynyl complexes exhibit interesting catenane structures, but their hetero-metallic catenane counterparts are under-developed. In this work, we report rare examples of bimetallic Au–Cu (DtbpC^C ligand; Dtbp 1⁄4 3,5-di-tert-butylphenyl), Au–Ag (BuC^C ligand), and Au–Cu, Au–Ag (C6FluoC^C ligand; C6-Fluo 1⁄4 9,9-dihexyl-9H-fluoren-2-yl) complexes as well as a trimetallic Au–Ag...

The preparation of heterodinuclear complexes, especially those comprising early-late transition metals coordinated by a simple or symmetrical ancillary ligand, represents a fundamental challenge and an opportunity to prepare catalysts benefitting from synergic properties. Here, two new mixed titanium(iv)-zinc(ii) complexes, [LTi(OiPr)2ZnEt] and [LTi(OiPr)2ZnPh], both coordinated by a diphenolat...

Chiral hexamine macrocycle derived from trans-1,2-diaminocyclohexane (DACH) in a complex with diethylzinc efficiently catalyzes the asymmetric hydrosilylation of N-phosphorylated aryl-alkyl or aryl-aryl ketimines in protic media with enantiomeric excess of the product approaching 100%. The cyclic structure of the trianglamine ligand increases the enantioselectivity and/or the yield of the react...

The terphspan scaffold was employed to support a bis(N-heterocyclic carbene) ligand () that provides a m-terphenyl canopy over one side of its metal complexes. Single-crystal X-ray diffraction studies on a silver complex of {[Ag()]AgBr(2)}(2) revealed an unusual tetranuclear silver core with a Ag-Ag bond distance of 3.0241(8) A with as a trans-chelating ligand (C-Ag-C = 171 degrees ). A prelimi...

In this paper, cubic nickel oxide nanoparticles were successfully prepared by solid-state thermal decomposition of nickel(II) macrocyclic Schiff-base complex at 450°C for 3 h without employing toxic solvent or surfactant and complicated equipment. nickel(II) macrocyclic Schiff-base complex was synthesized by the reaction of 1,2-bis(2-formyl-3-methoxyphenyl)propane, NiCl2•6H2O and 1,3-phenylened...

In the title centrosymmetric complex, [Ag(2)(ClO(4))(2)(C(10)H(7)N(3))(2)], the unique Ag(I) ion is coordinated by an N atom from a carbonitrile group, an N atom from a symmetry-related pyrazole group and an O atom of a perchlorate ligand to form a distorted T-shaped environment. Two 3-(1H-pyrazol-1-yl)benzonitrile ligands each bridge two Ag(I) ions to form a dinuclear complex. In the crystal s...

The dinuclear title complex, [Ag2(C6H7N2S)2(C18H15P)2], comprises two inversion-related [Ag(C6H7N2S)(C18H15P)] units. The pyrimidine-thiol-ate anion acts both as a bridging and a chelating ligand. The Ag(I) ions are linked via two μ2-S donor atoms, which generate a strictly planar Ag2S2 core with an Ag⋯Ag separation of 2.9569 (4) Å. The Ag(I) ion presents a distorted tetra-hedral coordination g...

Macrocyclic complexes of co(III) of the type, CoCy1-2B’X where Cy1 represents themacrocyclic ligand 1,8-dichloro-2,7,9,14-tetraoxa-1,1,8,8-tetraisopropoxy4,5,11,12-tetramethyl-1,3,6,10,13tetraaza, cyclotetradeca-3,5,10,12tetrene[boimacylene(14)] and cy2-represents the macrocyclic ligand 1,8-dibora2,7,9,14-tetraoxa -1,1,8,8-tetraisopropoxy 4,5,11,12-tetraphenyl-1,3,6,10,13Tetraazacyclotetradeca-...

Nanoparticles of a new dinuclear silver(I) complex [Ag2(PPh3)2(μ-S-4nb-tsc)2(η1-S-4nb-tsc)2](NO3)2, where 4nb-tsc = 4-nitrobenzylidenethiosemicarbazone and PPh3 = triphenylphosphine, were prepared in an ultrasonic bath and characterized by FT-IR and SEM. The crystal structure of a suitable single crystal prepared by slow evaporation was determined by single crystal X-ray diffraction. The compou...
