A new route to tetrachloro-complexes of the type trans-[OsCl4L2] from mer-[OsCl3L3](L = tertiary phosphine or tertiary arsine) is described, which involves treatment with chlorine in the presence of light. The tetrachloro-osmium(III) complex trans-[OsCl4(PMe2Ph)2] reacts with tertiary phosphines, tertiary arsines, alkyl phosphites, or alkyl phosphonites (L′) to give [OsCl3(PMe2Ph)2L′]. Reduction of

The series of crystalline, mononuclear B/sup +/(MO(XR)/sub 4/)/sup -/ and triplybridgedbinuclear B/sup +/(M/sub 2/O/sub 2/(XR)/sub 6/(OMe))/sup -/(M = Mo, W; X = S, Se; R = aryl; B = quaternary cation) salts have been isolated and the anions (MoO(SR)/sub 4/)/sup -/ (R = Et, CH/sub 2/Ph) stabilized in solution at -60/sup 0/C. The mononuclear anions are intensely colored due to a ligand-to-metal charge-transfer

Reduction of A[Co(CO)4] by three equivalents of A (A = sodium or potassium) in liquidammonia provides salts containing tricarbonylcobaltate(3 -). A satisfactorily pure sodium compound, Na3[Co(CO)3] is described for the first time. Reactions of A3[Co(CO)3] with two equivalents of Ph3ECl (E = Ge, Sn, Pb) provides 50–70% yields of trans-(Ph3E)2Co(CO)3− which have been isolated as analytically pure Et4N+

Contrary to an earlier report, the interaction of BF3 with SnCl3− or GeCl3− does not lead to the formation of simple complexes such as Cl3SnBF3. The reaction which does occur may be described as Cl− transfer from a weak Lewis acid, MCl2 (M = Sn or Ge), to a stronger Lewis acid, BF3; viz SnCl3− + BF3 = SnCl2 + BF3Cl−.

The new cluster species [Os11C(CO)27]2–(2) has been identified as one of the products resulting from the pyrolysis of [Os3(CO)12]. It reacts with [Cu(NCMe)4] BF4 to yield the monoanion [Os11C(CO)27Cu(NCMe)}]–(4) and [Os11C(CO)27Cu(NCMe)}2](5). The reaction of (2) with iodine-iodide produces a series of iodo-clusters [Os11C(CO)27I]–(8) and [Os11C(CO)27I2](9) which are converted back into (2) by addition
