... Unfortunately, we were unable to grow X-ray quality crystals of 1 and 2. However on the basis of spectral evidences, it may be anticipated that each thiazolato ligand coordinates to one metal center to form a four membered chelate ring. As a whole, compounds 1 and 2 are binuclear metal complexes wit ...

apch19 Introduction to Entropy POGIL
... Entropy (abbreviated “S”) is a measure of the number of states a system can have. However, because the more states a system can have means that it is more like to be found in a disordered state, we often just say that entropy is a measure of disorder. (Notice that entropy is related to disorder, not ...
