Azide complexes of Ga(III) have attracted con­ siderable attention in recent years owing to their importance as precursors for the formation of GaN [1-4] . Gallium nitride is a rather stable III-V semi­ conductor with interesting optical properties which can be utilized for optoelectronic applications in­ cluding blue light-emitting diodes and lasers [5 7]. The thermal decomposition of Ga(N3)3 ...

[Ru(terpy)(bpy)(L)]PF6 complexes, where terpy is 2,2 ́:6′,2′′– terpyridine, bpy is 2,2 ́ bipyridine and L is monoanions of 4 bromophenylcyanamide (4 Brpcyd), 4methoxyphenylcyanamide (4 MeOPcyd), 2, 4 dibromophenylcyanamide (2,4 Br2pcyd), 2,4dimethylphenylcyanamide (2,4 Me2pcyd), 2 methylphenylcyanamide (2 MePcyd), phenylcyanamide (Pcyd) and naphtylcyanamide (ncyd) have been prepared and character...

To obtain luminescent lanthanide complexes with a low energy LMCT state the 2-(2'-mercaptophenyl)benzothiazolates, Ln(SSN)3, and 2-(2'-mercaptophenyl)benzoxazolates, Ln2(OSN)6 (Ln = Gd, Yb), were synthesized by the reaction of amides Ln[N(SiMe3)2]3 with respective thiophenols. Ytterbium complexes were structurally characterized by X-ray diffraction analysis. Cyclic voltammetry revealed that the...

We describe the synthesis, solid state and solution properties of two families of uranyl(VI) complexes that are ligated by neutral monodentate and anionic bidentate P=O, P=NH and As=O ligands bearing pendent phenyl chromophores. The uranyl(VI) ions in these complexes possess long-lived photoluminescent LMCT (3)Π(u) excited states, which can be exploited as a sensitive probe of electronic struct...

Recently synthesized by the group of Sadler, the platinum(IV) diazido complexes [Pt(N(3))(2)(OH)(2)(L')(L'')] (L' and L'' are N-donor ligands) have potential to be used as photoactivatable metallodrugs in cancer chemotherapy. In the present study optimized structures and UV-Vis electronic spectra of trans,trans,trans- and cis,trans,cis-[Pt(N(3))(2)(OH)(2)(NH(3))(2)] (1t and 1c, respectively) as...

This article analyzes the electronic factors governing bond length alternation (BLA) in linear polyenes. The impact of various effects is illustrated on small all-trans polyenes, namely butadiene, hexatriene and octatetraene prototype molecules. It well known that self-consistent-field single determinant treatments overestimate paper aims to identify physical correlation which correct this defe...
