The intermetallic Y11Co4In9 compound has been synthesized, and its crystal structure and magnetic properties are reported. Powder X-ray diffraction measurements at room temperature and the Rietveld analysis show that the compound crystallizes in an orthorhombic Nd11Pd4In9 structure with Cmmm space group. Temperature dependence of the AC magnetic susceptibility indicates the broad maximum at 10 K while DC data give in this temperature separation on zero field cooled and field cooled susceptibility with the negative value of zero field cooled data. Above 10 K the DC magnetic susceptibility does not obey the Curie-Weiss law. The magnetization curve at 1.9 K does not show saturation at H=90 kOe, with the small value of the magnetic moment equal to 0.14 μB/f.u.
