title: Bis(piperidin-1-yl)methanone.
abstract: The title compound, C(11)H(20)N(2)O, is a urea derivative bearing two piperidine moieties in place of the amino groups. The mol-ecule shows approximate non-crystallographic C(2) symmetry. The six-membered rings adopt (1)C(4) and (4)C(1) conformations and their mean planes make a dihedral angle of 35.87 (5)°. In the crystal, inter-molecular C-H⋯O contacts connect the mol-ecules into infinite strands along the a axis.
