As reported by Shin‐ichi Ohkoshi and co‐workers on page 2089 a three‐dimensional Co‐W bimetallic assembly possessing two different aromatic molecules, [{Co II (4‐methylpyridine)(pyrimidine)} 2 {Co II (H 2 O) 2 }{W V (CN) 8 } 2 ]·4H 2 O, exhibits a photoinduced magnetization due to an optical charge‐transfer‐induced spin transition with a high Curie temperature ( T C ) of 48 K and a gigantic coercive field ( H C ) of 27 000 Oe. The T C and H C values are the highest reported for photoinduced magnetization systems.
