One- and Two- Dimensional Copper(I) Halide Based Coordination Polymers with Bridging Pyridazine or Pyrimidine Ligands
Z. Naturforsch. 54 b, 1175-1180 (1999); received June 9, 1999 Copper(I) Halides, Pyridazine, Pyrimidine, Coordination Polymers 1-Dimensional coordination polymers J. [CuX(/i-pydz)] 1 3 (X = Cl, Br, I; pydz = pyrid azine) may be prepared by self-assembly in acetonitrile solution at 120 °C (1) or room temper ature (2, 3). Individual chains contain (CuX)2 rings and dimeric [Cu(^-pydz) ] 2 substr...
متن کاملMetal-metal interactions in dinuclear ruthenium complexes containing bridging 4,5-di(2-pyridyl)imidazolates and related ligands.
The dinuclear bis(2,2'-bipyridine)ruthenium complex of 4,5-di(2-pyridyl)imidazolate has been prepared and separated into its (meso and rac) diastereoisomers. The 2-phenyl substituted analogue forms the meso isomer selectively. All three complexes have been characterised by 1H NMR and X-ray crystallography. Electrochemical measurements and spectroelectrochemistry of the mixed-valence states reve...
متن کاملReactions of the Tridentate and Tetradentate Amine Ligands di-(2-picolyl)(N-ethyl)amine and 2,5-Bis-(2-pyridylmethyl)-2,5 diazohexane with Technetium Nitrosyl Complexes.
The reaction of the Tc(II) nitrosyl complex (Bu(4)N)[Tc(NO)Cl(4)] with Di-(2-picolyl)(NEt)amine in methanol yields the neutral complex [Tc(NO)Cl(py-N(Et)-py)]. The reaction of the Tc(I) nitrosyl complex [Tc(NO)Cl(2)(HOMe)(PPh(3))(2)] with this tridentate ligand yields cationic [Tc(NO)Cl(py-N(Et)-py)(PPh(3))]Cl. These two complexes have been structurally characterized. The reaction of [Tc(NO)Cl(...
متن کاملCrystal structure of a dinuclear CoII complex with bridging fluoride ligands: di-μ-fluorido-bis{tris[(6-methylpyridin-2-yl)methyl]amine}dicobalt(II) bis(tetrafluoridoborate)
Reaction of Co(BF4)2·6H2O with tris-[(6-methyl-pyridin-2-yl)meth-yl]amiine in methanol results in a fluoride abstraction from BF4 (-), yielding the unexpected title compound, [Co2F2(C21H24N4)2](BF4)2. The complex cation consists of two inversion-related [Co(C21H24N4)](2+) moieties bridged by a pair of fluoride ligands. The Co(II) cation is six-coordinated in a distorted octa-hedral geometry and...
متن کاملPyrazolate-bridging dinucleating ligands containing hydrogen-bond donors: synthesis and structure of their cobalt analogues.
Convergent preparative routes to new urea-pyrazolate dinucleating ligands are described. Metal complexes of these ligands have hydrogen bond donors that are proximal to the metal centers that interact with other coordinated species. This is exemplified by Co(II) dimers with Co(II)-mu-Cl-Co(II) motifs, in which the chloro ligand is involved in four intramolecular hydrogen bonds. These noncovalen...
