Three-in-one: the novel packing and structures of three independent molecules of a tricyclic boron compound
摘要:
The three independent molecules in a single crystal of the tricyclic compound 15-[3-(dimethylamino) propoxy]-5,5,13,13-tetramethyl- 1,7,9,14,16-pentaoxa-5,13-diazonia-15-bora-6,8-diboratadispiro[ 5.1.5.3] hexadecane, C15H36B3N3O6, are bound in dense layers by C - H center dot center dot center dot O( B) intermolecular interactions. The 3-( dimethylamino) propoxy arms adopt three different conformations with only van der Waals contact distances between the layers. The replicated differences in the B - N bond lengths [ mean 1.723 ( 7) and 1.678 ( 5) angstrom] for equivalent geometries are addressed using density functional theory (DFT) calculations.
