摘要: Abstract Three new compounds containing adamantylcarboxylate ligands, [Ru2(C10H15CO2)4(CH3OH)2]·2CH3OH (1), [Ru2(C10H15CO2)3(CO3)(CH3OH)2]·2CH3OH (2) and Mo2(C10H15CO2)4(C4H8O)2 (3), have been prepared by reacting K3[Ru2(CO3)4]·4H2O, K4Mo2Cl8 Mo2(OAc)4 with C10H15CO2H. Their crystal structures determined. Crystals are as follows. 1: space group P21/c, a=12.966(2), b=16.541(4), c=12.573(3) A, β=118.77(2)°, V=2364(1) A3, Z=2, Ru-Ru distance = 2.2809(9) A. 2: P212121, a=13.062(1), b=26.375(4), c=11.943(2) V=4115(1) Z=4. The is 2·254(8) 3: P1, a=12.897(2), b=17.308(2), c=11.927(1) α=107.703(9), β=92.06(1), γ=93.01(1)°, V=2529.0(6) Z=2. average Mo-Mo 2.083[2] formation of 1 from the starting tetracarbonato complex appears to involve disproportionation 2Ru25+ Ru24+ 2Ru3+.
