A review of literature values for nitrosyl complexes with various ligands bound to the coordination sitetrans- to the nitrosyl group shows only minor variations in the M-N-O bond angle.

A single new complex is reported, the ReI-NO complex [ReICl2(NO)(py-N(Et)-py)], in which the tridentate ligand di-(2-picolyl)(N-ethyl)amine, (py-N(Et)-py), is coordinated in a meridional manner. This complex was synthesized from the reaction of the ReI-nitrosyl complex ReCl2(NO)(NCMe)3] and the neutral tri-amine ligand py-N(Et)-py in methylene chloride under argon. The bright red species was isolated chromatographically and recrystallized from CH2Cl2/MeOH under diethylether.

An experiment involving synthesis and spectral studies of a series of [Co(NH3)5L] complexes that introduces general chemistry students to inorganic synthesis and allows them to conduct a systematic study on the effect of different ligands on absorption spectra.

Synthesis And Analysis Of Cobalt

Systematical investigations of the coordination properties of these ligands, with different denticity, unexpectedly showed, based on numerous complexes[10,11], that the isothiosemicarbazon fragments used the thioamide nitrogen atom for coordination instead of the sulfur atom.

Reactions and Applications of Coordination Compounds

An undergraduate chemistry laboratory project involving the synthesis of [Ag(NH₃)₂]₂SO₄ and Cu(NH₃)₄SO₄ from the simple sulfate salts is described. Characterization of the stoichiometry of the complexes is accomplished by gravimetric and volumetric analysis. Silver is precipitated as the chloride and copper is precipitated as the hydroxide and converted to the oxide before weighing. The ammonia content of each complex is determined with a back titration using dilute nitric acid and sodium hydroxide. Typical student work gives results for the stoichiometry of the complexes within 1-5% of the theoretical values. The project provides a convenient preparation of two compounds whose identity and formula will not be obvious to the student. The analytical procedures illustrate the fundamentals of gravimetric and volumetric analysis and some basic characteristics of simple coordination complexes. The analytical data allow the student to determine the identity of each product by determining its empirical formula.
