which a symmetrical arrangement can obtain with 5 or 7 units; according 

 to Hiittig, 525 symmetrical arrangements can also occur with coordination 

 numbers of 12 and 20. 



In studies of the various acids, the coordination numbers most frequently 

 noted were likewise 4, 6, and 8, but values of 2 and 3 were found in the case 

 of some short-chained acids, and a value of 1 was noted for acetic acid. In no 

 case was any evidence adduced for the occurrence of choleic acids with 5 or 

 7 units, or of high molecular aggregates containing 12 or 20 units. The
