I do not know about web links, but Cosmos 2221 is a Tselina-D electronic intelligence-gathering satellite - part of a long series which started with Cosmos 389 in 1971. Launches originally used the Vostok-2M vehicle but in the early 1980s switched to the three-stage Tsyklon. As far as I am aware, no illustrations are available of the satellite.
