Donor-Acceptor Interactions in Crystal Engineering
The molecular complex formed between 4-methyltolane and bis(4-N-methylpyridinium)ethyne ditriflate is reported. The X-ray crystal structure indicates that the crystalline superstructure consists of infinite zigzag ribbons of interlocked donor-acceptor complexes separated by triflate counterions.
