A new approach for the synthesis of low valent metal sandwich complexes showing the unanticipated ease with which silylamides can function as leaving groups resulting in a 1D polymer of the repeating unit, [K(18-crown-6)][Cr2(C10H8)2], has been described.

X-ray diffraction studies have revealed that K4UO2(CO3)3 is isostructural with (NH4)4UO2(CO3)3; the crystal is monoclinic with a = 10.247(3), b = 9.202(2), c = 12.226(3) Å, β = 95.11(2)°, Z = 4, and space group C2/c. Three carbonate anions are arranged in bidentate fashion in the equatorial plane of UO22+; one of these occupies a C2 site and the other two occupy C1 sites. All carbonates are significantly distorted from D3h symmetry. The binding of carbonates to uranyl is strong and thus the lattice can be considered to be composed of [UO2(CO3)3]4− anions and K+ cations. The Raman and infrared spectra exhibit fewer lines than predicted for such a crystal. Tentative assignments are suggested for the more prominent bands of the constituent polyatomic species.

The preparations of complexes of the type L2M(RC2R′) (where L = Ph3P, M = Ni, Pd, Pt, R = R′ = CF3; L = Ph3P, M = Ni, Pt, R = R′ = Ph, and R = Ph, R′ = Me; L = Ph3P, M = Pd, Pt, R = R′ = COOMe; and R = R′ = CF3, M = Pd, Pt, L = n-Bu3P, Mc2PhP) are described. From their nuclear magnetic resonance spectra these complexes appear to be approximately planar in solution. The VC≡C observed in their infrared spectra indicate strong bonding of the acetylene to the metal.A new approach to the bonding in metal–acetylene complexes is proposed which can be extended to other π-complexes and which allows some predictions to be made.
