N,N'-BIS(SUBSTITUTED)-4,13-DIAZA-18-CROWN-6 DERIVATIVES HAVING PI-DONOR-GROUP-SIDEARMS: CORRELATION OF THERMODINAMICS AND SOLID STATE STRUCTURES

Article abstract of DOI:10.1016/0040-4039(88)85076-7

Solution thermodynamic data and solid state structure information are used to show that a series of N,N'-bis(substituted)-4,13-diaza-18-crown-6 (BiBLE) derivatives which lack oxygen or nitrogen donor groups in the sidearms do not utilize the sidearms for binding but show considerable variation in their binding constants.
