# New crystal structure of molecular complex 1-piperidine carboxylate-piperidinium-H2O studied by X-ray single crystal diffraction

Piperidine absorbs CO2 and H2O in air to form a molecular complex: piperidium-1-piperidinecarboxylate-H2O. The structure of the complex was characterized by X-ray single crystal diffraction. The crystal structure was determined to be triclinic, space group P $$\bar 1$$ with a=0.648 6(8) nm, b=0.809 2(10) nm, c=1.357 1(16) nm, α=96.967(16)°, β=102.506(15… CONTINUE READING
