A new metaorganic compound was studied under picosecond laser by Z-scan technique. The third order nonlinearity and optical limiting properties of it was obtained from the experiment result.The χ (3) value was 3.8×10 -14 esu ,and it had two-photon absorption .The optical limiting experiment result showed that two different mechanisms including two photon absorption and nonlinear refraction determined its optical limiting property.
