摘要：

For the exploration of the organometallic chemistry of divalent chromium, the readily synthesized Cr(II) complex 1 is a simple starting material. The chloro bridges can be exchanged for alkyl groups (R = Me, nBu, CH2SiMe3), and the resulting complexes 2 react with H-2 to give the tetranuclear hydrido complex 3 with a cubane structure. Unexpectedly, 3 shows almost ideal Curie paramagnetism according to magnetic measurements.
