Thermally stable potassium N-heterocyclic carbene complexes with alkoxide ligands, and a polymeric crystal structure with distorted, bridging carbenes.

چکیده
Alkoxide-functionalized N-heterocyclic carbenes (NHCs) stabilise the potassium-imidazole-2-ylidene fragment against 1,2 alkyl rearrangement reactions; this allows the first structural characterisation of a potassium NHC complex, which reveals distorted and unusual bonding interactions between the imidazole ring and the potassium cation.

Main-chain organometallic polymers comprising redox-active iron(II) centers connected by ditopic N-heterocyclic carbenes.
Main-chain organometallic polymers were synthesized from bimetallic iron(ii) complexes containing a ditopic N-heterocyclic carbene (NHC) ligand [(cp)(CO)LFe(NHC approximately NHC)Fe(cp)(CO)L]X(2) (where NHC approximately NHC represents a bridging dicarbene ligand, L = I(-) or CO). Addition of a diimine ligand such as pyrazine or 4,4'-bipyridine, interconnected these bimetallic complexes and gav...
متن کاملNanofiber Composites Containing BIAN N-heterocyclic Gold Carbene Complexes and Cytotoxicity in Human Cancer Cells
A carbene is a divalent carbon atom linked to two other groups by covalent bonds, and possesses two unshared valence electrons. These electrons can be paired in the same orbital as anti-parallel spins (singlet) represented as σ2 or pπ2 in different orbitals, or as parallel spins (triplet) represented as σ1 pπ1. (Droge and Glorius, 2010). N-Heterocyclic carbenes (NHCs) are singlet carbenes in wh...
متن کاملPiano-Stool Iron(II) Complexes as Probes for the Bonding of N-Heterocyclic Carbenes: Indications for π-Acceptor Ability
A series of new piano-stool iron(II) complexes comprising monoand bidentate chelating N-heterocyclic carbene ligands [Fe(cp)(CO)(NHC)(L)]X have been prepared and analyzed by spectroscopic, electrochemical, crystallographic, and theoretical methods. Selectively substituting the L site with a series of ligands going from carbene to pyridine to CO suggests that CO is the strongest π acceptor, whil...
متن کاملElectronic Structure and Reactivity of Metal Carbenes
Metal carbenes have for a long time been classified as Fischer or Schrock carbenes depending on the oxidation state of the metal. Since the introduction of N-heterocyclic carbene complexes this classification needs to be extended because of the very different electronic character of these ligands. The electronic structure of these different kinds of carbene complexes is analysed and compared to...

The polymeric compound, {(C10H9N2)[Mn(C7H3NO4)2].(C10H8N2).6H2O}n, was prepared by the reaction of manganese (II) nitrate with pyridine-2,3-dicarboxylic acid, (py-2,3-dcH2) and 4,4'-bipyridine (4,4'-bipy) in a 1:2:4 molar ratio. The crystal system of the complex is monoclinic with space group P21/n and four molecules per unit cell. The unit cell parameters are: a = 22.2099(15) Å, b = 6.6599(4)...
