_exptl_crystal_mounting_method
'Crystals were removed from the crystallisation vial and immediately coated with polybutenes oil (CAS: 9003-29-6) on a glass slide. A suitable single crystal coated with polybutenes oil as less as possible was sealed in capillary tube filled with argon. The capillary tube with single crystal was mounted on copper pin with solid paraffin.'
