The session "Inorganic Compounds" is one from very traditional sessions of ECM's containing always a lot of contributions. The ECM-18 was not an exception, more than 15% of all posters were presented here. On the other hand it can be considered as a mother session of the other ones, because "Aperiodic Crystals and Quasicrystals" or "Optic, Electric and Magnetic Materials" and many others are mostly nothing else than "Inorganic Compounds". This is very unfavourable for this session, because whenever something interesting happens in the inorganic world a new, child, session is born. A review lecture on the "Inorganic Crystallography" was given by Venceslav Kaucic from Ljubljana, therefore the programme of the session was planned rather as a collection of interesting experimental results. Twice as many oral contributions as time available were submitted, therefore a selection had to be done, trying to cover as broad spectrum of problems as possible. Two lectures were devoted to the intermetallic compounds: "Structure of the Cobalt/Nickel - Containing Aluminides with Filled Pentagonal Clusters" (M. Ellner) and "Phase Stability and Some Physical Properties of the YbCu₅-Related Intermetallics" (K. Kosuge). They have demonstrated the large structural variety and still many unknowns in the intermetallic world. Several lectures gave a small review of particular fields in the inorganic crystallography: "Structure Analysis of Intercalates" (P. »apkov·), "Crystallochemistry of Non-Linear Pseudohalides in Copper(II) Complexes" (M. Dunaj-JurËo) and "Anion-Centred Tetrahedra in Inorganic Compounds" (S. Filatov). Importance of the structure analysis for the applications was clearly demonstrated in the lecture "Crystal Structures and Physical Properties of Compounds in the Phase-System Ln₂O₃-ReO₂-Re₂O₇" (H. Ehrenberg). Usefulness of the bond-valence concept in the inorganic crystallography was shown in the lecture "Bond Lengths and Bond Valences in (Ba_0.875Sr_0.125)RuO₃, BaRuO₃ and Ba₃MRu₂O₉ (M=Fe,Co, Ni, Zn, In)" (A. Santoro). The subjects which was possible to meet during the poster session can be divided into three categories: analysis of difficult structures, systematic of structures and relation structure/properties. The studied compounds involved all compounds which we call "inorganics" with a strong accent on intermetallics, metalorganics and oxides or salts.
