چکیده
The reaction of Cu(dmp)2 with NO has been investigated for potential development into an optical fibre chemical sensor. In aqueous solutions, a linear calibration (r= 0.9950) was obtained between 0 and 2.5 M NO with a detection limit of 0.32 M (∼0.0096 ppm) (s/n = 3). The complex electrostatically immobilised in nafion produced a highly linear calibration (r= 0.999) between 0 and 3 ppm in NO gas phase with a detection limit of 0.072 ppm (∼2.38 M in solution). The response was shown to be fully reversible by immersing the films in hydroxylamine h s ©

Gravimetric, titrimetric, polarographic, optical and radiochemical methods have been reported for the determination of iron(II) and (III). Numerous reagents have also been reported for the spectrophotometric determination of Fe(II); for example, thiocyanate, dipyridine, tripyridine and 1,10-phenanthroline. The 1,10phenanthroline family has been extended to the use of dihydroxy, dimethyl, nitro ...

In the title compound, [CuCl(2)(C(14)H(12)N(2))], the complex molecule has m symmetry, with the mirror plane oriented parallel to the planar molecule and the ligated Cu(II) atom. The metal centre has a distorted tetra-hedral coordination formed by two N atoms from one 2,9-dimethyl-1,10-phenanthroline ligand and two Cl atoms. There is inter-molecular π-π stacking between adjacent 2,9-dimethyl-1,...

The asymmetric unit of the title complex [Cu(C14H12N2)2]2[Fe(CN)5(NO)], consists of a [Cu(dmp)2](+) cation (dmp is 2,9-dimethyl-1,10-phenanthroline) and half an [Fe(CN)5(NO)](2-) anion. The anion is disordered across an inversion center with the Fe(II) ion slightly offset (ca 0.205Å) from the inversion center in the direction of the disordered trans-coordinating CN/NO ligands. The anion has a d...
