Chinese lantern structure

In chemistry, the Chinese lantern structure is a coordination complex where two metal atoms are bridged by four bidentate ligands. Examples include chromium(II) acetate, molybdenum(II) acetate, and rhodium(II) acetate, copper(II) acetate dihydrate. The name reflects a resemblance between the structure and a Chinese paper lantern. Often these compounds bind additional ligands at the sites across from the M---M vector. The degree of metal-metal bonding varies according to the d-electron configuration.[1]
