To complete the students’ practical training in Inorganic Chemistry. So, it is intended to:
a) Acquaint the students with synthesis and purification techniques of average difficulty.
b) Introduce the students into the use of the most common characterization methods in Inorganic Chemistry, insisting on the most basic theoretical aspects.
c) Make students to acquire a good command in the use of bibliographical sources about Inorganic Chemistry. Contents
It is required to carry out at least one of the practices from the following points:
Fundamentals of coordination chemistry:
- Spectrochemistry series: Hexacoordinated copper (II) complexes.
- Bond isomerism: pentaaminnitrocobalt (III) chlorides
- Cis-trans isomerism: Dichlorobis (ethylendiamine) cobalt (III) chlorides.
Synthesis and characterization of coordination compounds:
- Werner complexes.
- Sodium tris(carbonate) cobaltate (III)
- [Co(salen)] and its interaction with dioxigen.
- Trichloretripyridinchrome (III).
- Dichlorobis (pyridine) cobalt (II).
- Bis (acetyl acetonate) copper (II).
- Tris (acetyl acetonate) aluminium (III).
- Tris (acetyl acetonate) manganese (III).
- Oxovanadium (IV) bis acetyl acetonate. Study of the influence of solvents in the electronic spectrum.
- Sulphate as contraion and uni- and bi- jagged ligand in different complexes: IR study.
Synthesis and characterization of materials in solid state.

Alternately, it may be proposed to do a synthesis and characterization of some of the following metalorganic compounds:
- Ferrocene monoacetyl.
- Ferrocene diacetyl.
- Triphenilphosphine and Ni(PPh3)2Cl2
- Dichloro-dietil-tin (IV) and its adduct with dimetilsulfoxide.
- Tetra-etil-tin (IV)
Any of the practices can be substituted by any other similar one.Basic and complementary bibliography

The following abilities are intended to be developed:
- To promote the knowledge of usual bibliographical sources used in Inorganic Chemistry (textbooks, manuals, series, great treatises, practices books, index magazines, research magazines (paper and on-line) and the usual ways of acceding at them (library, internet, …).
- To interpret the synthesis methods described in the bibliography and learning to program a laboratory experiment.
- To know and be able to use advanced techniques in Inorganic Chemistry (vacuum line, dry box, solvent drying…)
- To initiate into the basic characterization techniques of inorganic compounds (preparation of samples and interpretation of results).
- Ability for extracting conclusions about the purity and structure of the prepared compounds.
- Ability for presenting the obtained results clearly.Teaching methodology
The first day, apart from working at the laboratory, the students will be informed about the laboratory safety rules, the subject’s objectives, the practices’ development, assessment criteria, etc. It will also be done a brief theoretical presentation to characterization techniques. We will also solve some problems similar to those that students find in the laboratory when doing the different experiments.
Since this is an experimental subject, the students will choose some of the practices included in the syllabus. The number of practices to do will depend on their complexity and the student’s ability to carry them out.
The student’s carrying out of the practices implies the following:
a) Bibliographical revision and theoretical preparation of the experiment;
b) Carrying out of the experiment at the laboratory (in general, synthesis and purification of a compound).
c) Characterization of the compound obtained by means of the experimental techniques that are usual in Inorganic Chemistry and discussion of the results.
d) Carrying out of the laboratory report.Assessment system
The student’s final assessment will be based on the continuous assessment during the practices’ development. This mark will try to reflect the student’s ability and interest on the laboratory work, valuing not only the achievement, the degree of purity of the prepared products and the discussion about the results, but also other collateral matters as the students’ manual skills, the respect to the safety rules and the general cleaning and care of the laboratory.
That mark will be complemented with the mark given to the laboratory report done by the student.
If there are more than 5 registered students, the mark will be completed by the result obtained in a final exam at the end of the semester.
Those students who miss more than 10% of the present sessions will be assessed as “Not presented”.Study time and individual work
