The bulk single crystals of S=1 chain compound Ni(C3H10N2)(2)NO2ClO4 are grown by using a slow evaporation method at a constant temperature and a slow cooling method. It is found that the optimum condition of growing large crystals is via slow evaporation at 25 degrees C using 0.015 mol Ni(ClO4)(2)center dot 6H(2)O, 0.015 mol NaNO2, and 0.03 mol 1,3-propanediamine liquid dissolved into 30 ml aqueous solvent. High-quality crystals with size up to 18 x 7.5 x 5 mm(3) are obtained. The single crystals are characterized by measurements of X-ray diffraction, magnetic susceptibility, specific heat and thermal conductivity. The susceptibilities along three crystallographic axes are found to exhibit broad peaks at similar to 55 K, and then decrease abruptly to zero at lower temperatures, which is a characteristic of a Haldane chain system. The specific heat and the thermal conductivity along the c-axis can be attributed to the simple phononic contribution and are analyzed using the Debye approximation. (C) 2011 Elsevier B.V.
