Popis:	The structure of the compound of empirical formula (Et2O)2Cd(B10H12) has been investigated by X-ray diffraction techniques from diffractometer data. Crystals are triclinic, space-group P1 with one dimeric unit in the unit cell of dimensions a= 9·386(13), b= 10·854(18), c= 10·202(17)A, α= 90·07(9)°, β= 105·60(9)°, and γ= 102·80(8)°. Because of disorder in the positions of the ethyl carbon atoms, the structure was not solved completely (final R 9·8 % for 3423 independent reflections), but the dominant features have been elucidated; the molecules are dimeric, each cadmium atom being bonded (via three-centre bonds) to two B10H12 icosahedral fragments. The co-ordination environment of each cadmium is completed by two ether ligands. The two B10H12 units therefore act as bridges between the metal atoms and can be considered to be related to decaborane by replacement of two bridging hydrogen atoms by the cadmium atoms.
