Various types of non-covalent interactions contributing towards crystal packing of halogenated diphospha-dicarbaborane with an open pentagonal belt†
Abstract
We have prepared 3-Cl-10-I-nido-7,8,9,11-P2C2B7H7 by the reaction of 3-Cl-nido-7,8,9,11-P2C2B7H8 with I2 in the presence of AlCl3. The product was obtained in a yield of 49% and was characterized by NMR spectroscopy and X-ray crystallography. Quantum chemical calculations have demonstrated that the crystal structure is stabilized by hydrogen, dihydrogen and pnictogen bonds.
