“…Consequently, the shortness of the Cu-N(5) bond distance in (1) is primarily an artifact of the route B distortion present and cannot necessarily be associated with the potentially x-bonding role of the thiocyanate ligand. Thus the square-pyramidal distorted trigonal-bipyramidal structure of ( 1) may be related to the more regular trigonal-bipyramidal CuN,N',N'' chroinophore by the structural pathway of Figure 1, resulting from a linear combination of the v3, v4, v7, and vs normal modes of vibration of a trigonal-bipyramidal structure [FiguIe 3(b),ref.…”

The crystal structures of bis(2,2'-bipyridyl)monoiodo- The crystal structure of bis(2,2'-bipyridyl)monoiodocopper(II) iodide (Barclay, Hoskins & Kennard, 1963) was the first crystal structure in which it was established that the [Cu(bpy)2X] ÷ cation involved a five-coordinate trigonal-bipyramidal stereochemistry (bpy = 2,2'-bipyridyl). Owing to the presence of the heavy I atom and the use of visually estimated data the final R (0.09) was relatively high and the Cu-N distances, 1.96-2.10 A, were not considered significantly different. As the electronic spectra of a series of [Cu- Crystal dataThe crystal and refinement data for (I) and (II) are summarized in Table 1. For both complexes the preliminary cell dimensions and space group were determined from precession photographs and refined on a Philips PW 1100 four-circle diffractometer. The intensities were collected on. the diffractometer with graphite-monochromatized Mo Ka radiation. A 0-20 scan mode was used and reflections with 3-0 < 0 < 32 ° in one quadrant were examined. A constant scan speed of 0.05 o s-1 was used with a variable scan width of (0.7 + 0

“…The complex [Cu(phen) 2 ] 2+ is in coordination equilibrium with acetate ion at the two vacant coordination sites. 31 As we do not have the complex formation constants of Co(II)-VPy in methanol and the combination constants of copper or cobalt with VPy at polymer at present, the quantitative comparison of the stabilities of phen-Cu(II)-VPy and phen-Co(II)-VPy will be P(phen-Co-VPy) Pinky gray a The wavelengths were measured using methanol as reference. The absorbance of 2.00 mmol copper(II) acetate, cobalt(II) acetate and their complexes in 15 ml of methanol were too strong, so the present results were obtained from their 10-fold methanol-diluted solutions.…”

A functional polymer for the catalysis of the chemiluminescent reaction and molecular recognition ability of 1,10-phenanthroline was prepared based on the molecular imprinting method. The structural and catalytic roles of transition metal ion interactions were applied in the material design. A ternary complex, 4-vinylpyridine-Cu(II)-1,10-phenanthroline (2:1:1), was synthesized and used as a functional monomer. The ligand 1,10-phenanthroline in the ternary complex was the template used to form the molecularly imprinted polymer. Another monomer, styrene, and the cross-linking reagent divinylbenzene were copolymerized with the ternary complex. The polymer containing the ternary complex is an efficient catalyst for the decomposition of hydrogen peroxide. During the hydrogen peroxide decomposition, superoxide radical ion is formed, which reacts with 1,10-phenanthroline and gives a chemiluminescent emission. The 1,10-phenanthroline was destroyed during the chemiluminescent reaction, leaving a cavity and copper binding sites for another 1,10-phenanthroline molecule. The prepared polymer particles were packed into a glass tube and developed as a molecular recognition chemiluminescent flow-through sensor for 1,10-phenanthroline. The sensitivity and selectivity of the sensor were tested.
