The chloroarsinidene compound Cp'(CO)2Mn-As(Cl)-Mn(CO)2Cp', 1a, (Cp' = eta-5-C5H4CH3) upon reaction with GaCl3 transforms into the tetrachlorogallate of the dimanganaarsacumuleniumion [Cp'(CO)2Mn = As = Mn(CO)2Cp']+, 2a. The cumulene type bonding in 2a is evidenced by the spectroscopic and structural (X-ray analysis of 2a.GaCl4-) properties. The chloroarsinidene compound (CO)5Cr-As(Cl)-Cr(CO)5, 1b, and the chlorostibinidene complex Cp-star-(CO)2Mn-Sb(Cl)-Mn(CO)2-Cp-star, 1c, (Cp-star = eta-5-C5(CH3)5) are correspondingly transformed into dimetallaarsa- ([(CO)5Cr = As = Cr(CO)5]+, 2b) and dimetallastiba- ([Cp-star-(CO)2Mn = Sb = Mn(CO)2Cp-star]+, 2c) cumuleniumions respectively. The cations 2b, 2c are unequivocally characterized by spectroscopic techniques; however, crystal structure analyses could not yet be obtained.Under similar conditions the chlorostibinidene compound Cp'(CO)2Mn-Sb(Cl)-Mn(CO)2Cp', 1d, gives the trinuclear cation [Cp'(CO)2 activative Mn]-Cp'(CO)2Mn-Sb = Mn(CO)2Cp'+, 4, which, as shown by X-ray analysis of 4.CF3SO3-, contains a trigonally planar coordinated Sb+-cation.

The dimetallaarsacumuleniumion [Cp'(CO)2Mn = As = Mn(CO)2Cp']+, 2, which is easily obtained by halide abstraction from the arsinidene complex Cp'(CO)2Mn-As-(Cl)-Mn(CO)2Cp', 1a, reacts with nucleophiles X- to give the arsinidene species Cp'(CO)2Mn-As(X)-Mn(CO)2Cp', 1c-1f (1c: X = 1, 1d: X = NCO, 1e: X = NCS, 1f: X = N3); with BH4- as the nucleophile the parent compound Cp'(CO)2Mn-As(H)-Mn(CO)2Cp', 1b, is obtained.The new arsinidene compounds 1b-1f are characterized by the standard analytic and spectroscopic techniques; in addition X-ray analyses are reported for 1b, 1c and 1e.

The dimetallaarsacumuleniumion [Cp′(CO)2MnAsMn(CO)2Cp′]+, 2, (Cp′ = η5-C5H4CH3) obtained from the arsinidene compound , 1a, reacts with dipy to give the cationic arsenic(I) chelate compound [Cp′(CO)2Mn]2 As[dipy]+, which has been isolated and structurally characterized as its CF3SO3− salt, 3a. ortho-Phenanthroline as the chelate ligand gives the corresponding o-phen chelate, isolated as its triflate 3b.

AbstractTitle ions such as in (II) (space group P1, Z=2) are prepared by halide abstraction from the arsinidene compound (I).
