Weak Intermolecular Interactions in the (1:1)Pyridine Solvate of Dibenzotetraaza[14]annulene Copper(II) Complex.The Crystal Structure of [7,16-dibenzoyl-6,8,15,17-tetramethyl-5,14-dihydrodibenzo[b,i][1,4,8,11][tetraazacyclotetradecinato(2)-k~4N]coppe

摘要

Recrystallization of the title Cu(II) complex from pyridine afforded solid (1:1) pyridine inclusion compound.The crystal structure revealed a pleated-sheet-like arrangement of saddle-shaped molecules of the host,with molecules of pyridine enclathrated within intermolecular cavities.Careful analysis of intermolecular contacts showed that weak aromatic edge-to-face (C-H-O-pi) interactions occur between pyridine and host molecules.The crystal packing appeared to be also stabilized by the host-host C-H- O hydrogen bonds.
