摘要：
The pronounced melting point alternation of alpha,omega-alkanedicarboxylic acids (HOOC-(CH2)(n-2)-COOH, n=4-10) is maintained in co-crystals of the same acids with 1,2-bis(4-pyridyl)ethane (BPA), which contains an even number of carbon atoms in the chain, and is reversed in co-crystals with 1,2-bis(4-pyridyl) propane (BPP), which contains an odd number of carbon atoms in the aliphatic chain.
