In this data paper we present and characterise the multi-component radiosources identified in the VLA-COSMOS Large Project at 3 GHz (0.75 arcsecresolution, 2.3 {\mu}Jy/beam rms), i.e. the radio sources which are composed oftwo or more radio blobs.The classification of objects into multi-components wasdone by visual inspection of 351 of the brightest and most extended blobs froma sample of 10,899 blobs identified by the automatic code blobcat. For thatpurpose we used multi-wavelength information of the field, such as the 1.4-GHzVLA-COSMOS data and the UltraVISTA stacked mosaic available for COSMOS. We haveidentified 67 multi-component radio sources at 3 GHz: 58 sources with AGNpowered radio emission and 9 star-forming galaxies. We report 8 new detectionsthat were not observed by the VLA-COSMOS Large Project at 1.4 GHz, due to theslightly larger area coverage at 3 GHz. The increased spatial resolution of0.75 arcsec has allowed us to resolve (and isolate) multiple emission peaks of28 extended radio sources not identified in the 1.4-GHz VLA-COSMOS map. Wereport the multi-frequency flux densities (324 MHz, 325 MHz, 1.4 GHz & 3 GHz),star-formation-rates, and stellar masses of these objects. Multi-componentobjects at 3-GHz VLA-COSMOS inhabit mainly massive galaxies (>10^10.5 Msun).The majority of the multi-component AGN lie below the main-sequence ofstar-forming galaxies (SFGs), in the green valley and the quiescent region. Weprovide detailed description of the objects: amongst the AGN there are 2head-tail, 10 core-lobe, 9 wide-angle-tail (WAT), 8 double-double orZ-/X-shaped, 3 bent-tail radio sources, and 26 symmetric sources, while amongstthe SFGs we find the only star-forming ring seen in radio emission in COSMOS.We report a large number (32/58) of disturbed/bent multi-component AGN, 18 ofwhich do not lie within X-ray groups in COSMOS (0.08 < z < 1.53).
