C19H24N2 is orthorhombic,D24-P212121. Unit cell dimensions at 293 K area=10.346(7),b=10.464(3),c=29.083(10)Å,V=3149(4) Å3,Dc=1.18 g cm−3, andZ=8. The structure has been determined from single-crystal data collected with a four-circle diffractometer and refined from 1968 reflections down toR=0.045 andωR=0.047. The structural features determined from chemical and spectroscopic studies are confirmed and extended. There are two crystallographically independent molecules (A and B). In both A and B… Expand
