title: Low-temperature superstructure of [(N,N-diisobutyl-carbamo-yl)meth-yl]oct-yl(phen-yl)phosphine oxide (CMPO).
abstract: At 120 K, the title compound, C(24)H(42)NO(2)P, crystallizes in a unit cell with a doubled a parameter compared with the room-temperature structure. There are four mol-ecules in the asymmetric unit, one of which shows extensive disorder in a 0.588 (3):0.412 (3) ratio. In the crystal, numerous C-H⋯O inter-actions link the mol-ecules.
