Chemists were able to synthesize the five-olympic-ring molecule, the three interlocked Borromean rings, the football made of carbon atoms, the “cuban” −a hydrocarbon cube,“basketan” −in the form of an apple basket, the rotaxans shown in Fig. 13.2, a molecular in the form of ...
The key advantage of these methods is that the knowledge is stored in a machine-processable form. A core feature that the vast majority of KR formalisms share is the use of a well-defined syntax and semantics. The syntax serves as the alphabet of the language: it provides a set of ...

The elements hydrogen and oxygen combine to form a compound whose composition is expressed by the formula H2O. The molecule of water has the structure shown here. Chemical substances that cannot be broken down into simpler ones are known as elements. The actual physical particles of which elemen...
Octacyanofulvalenediide uses, in both compounds 4 and 6, all of its eight nitrile groups for coordination; in compound 6, four of them coordinate to two symmetry-related K+ ions each, which is similar to the situation found in [KC5(CN)5]. Therefore, both compounds form three-...
[4,5]. Under oxidizing conditions in the cell, copper exists as Cu2+, whereas reducing conditions favor the Cu+ form. Different behavior of the two states may be traced to differences in their hardness: whereas the Cu2+ ion is classified as a borderline Lewis acid, the reduced counterpart...
