Reaction of mercuric acetate with an imidazolium-linked cyclophane incorporating 2,6-phenolic moieties results in formation of an interesting new N-heterocyclic carbene (NHC) complex of mercury. The new complex is cationic and binuclear, incorporating two mercury centres and two bis(NHC) ligands, each mercury atom being bound by two NHC moieties and two phenol/phenoxy moieties. Forms of the com...

A series of six novel mononuclear, binuclear and linear one-dimensional (1D) compounds of copper(II) with chloranilic acid (3,6-dichloro-2,5-dihydroxybenzoquinone, H2CA) is prepared and a design strategy for the preparation of such complexes is discussed. Four described compounds are linear 1D coordination polymers [Cu(CA)]n, whereas another two involve a binuclear and a mononuclear, Cu2(CA)3 a...

a binuclear macrocyclic ligand containing dissimilar n(amine)2o2 and n(imine)2o2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor l1h2 with 1,3-diaminopropane. the ligand includes two propionitrile pendant arms on the amine nitrogen atoms. the homobimetallic complex [znl2zn(oac)]pf6 was synthesized by one step procedure. heterobim...

Binuclear diaminocarbene complexes, which form as a regioisomer mixture in the reaction between isocyanide–palladium(II) complex cis-[PdCl2(CNXyl)2] and 1,3-thiazol-2-amine, are able to exchange an anionic chloride ligand with other halides, such Br or I. This process also affords binuclear complexes mixtures of kinetically thermodynamically controlled regioisomers. In CDCl3 solutions, we obser...

The binuclear title complex, [Hg(2)(C(10)H(14)N(2)O(8))(2)(C(18)H(18)N(4))]·2CH(3)OH, lies on an inversion center with the unique Hg(II) ion coordinated in a disorted octa-hedral environment with one Hg-N bond significantly shorter than the other two. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link complex and solvent mol-ecules into a three-dimensional network.

The title complex, [Cu(2)(C(13)H(18)N(2)O(3))(2)]·C(3)H(6)O, has been synthesized by the reaction of copper(II) acetate monohydrate with 5,5'-bis-(diethyl-amino)-2,2'-[ethyl-enedioxy-bis(nitrilo-methyl-idyne)]diphenol, where one of the N-O bonds of the ligand was cleaved during the reaction. The complex mol-ecule has a μ-dialkoxo-bridged binuclear structure with both Cu(II) centers exhibiting a...

A novel boron complex bearing a pyrene ligand (CPB) was synthesized and introduced as the first example of a binuclear boron complex in organic light-emitting diodes. In the solid state, CPB2 exhibited strong red emission. In the devices, red emission with Commission International de L'Eclairage (CIE) coordinates of (0.57, 0.42) was obtained by tuning the weight concentration of CPB2. CPB2 beha...

The title compound, [Ru(2)(C(13)H(15)S)(2)(CO)(4)], is a centrosymmetric binuclear metal-carbonyl complex containing an Ru-Ru single bond [2.7511 (8) Å]. Each Ru(I) atom is coordinated by two bridging carbonyl ligands, one terminal carbonyl ligand and one η(5)-cyclo-penta-dienyl group. The complex has a trans conformation and the two cyclo-penta-dienyl ring planes are parallel. The crystal stru...
