The X-ray diffraction results show that the crystal structure of LiCu2O2 is orthorhombic down to T = 10 K. Anisotropic line-broadening of the diffraction peaks is observed, indicating disorder along the spin chains. Muon-spin relaxation and specific heat measurements show that LiCu2O2 undergoes a phase transition to a magnetic ordered state at T-1 similar to 24 K. The specific heat data exhibits a second lambda -like peak at T-2 similar to 32.5 K, which increases with increasing magnetic field in a similar way to that found in spin-ladder compounds.
