Description

Crystal structure of strontium nitrate complex with A isomer of dicyclohexyl-18-crown-6(DCH-6) was determined by the method of heavy atom (1252 reflections, diffractometer, MoKsub(α)-radiation) and refned by the least square method up to R=0.051. Rhombic lattice parameters: a=16.091 (5), b=14.830 (4), c--12.814 (10) A, sp. gr. P212121, rhosub(e)=1.59, rhosub(t)=1.603 g/cm3 at Z=4. The crystal is composed of [Sr(DCH-6)(NO3)2] complexes and solvate CCl4 molecules. The distance SA-Osub(dch-6) 2.66-2.85 A, Sr-Osub(NOsub(3)) 2.64-2.69 A. Coordination Sr polyhadron-irregular decavertex. Peculiarities of conformation of dicyclohexyl-18-crown-6 are discussed
