As the foundation to a survey of interactions between chromium(III) and lanthanide(III) ions within the same crystal lattice, a series of complexes of stoichiometry [Cr((NH2)2sar)]- [ Ln ( dipic )3].8H2O (sar = 3,6,10,13,16,19-hexaazabicyclo[6.6.6] icosane, Ln = La-Lu plus Y, dipic = pyridine-2,6-dicarboxylate) has been synthesized and structurally characterized by room-temperature single-crystal X-ray studies. An isomorphous series is found for all Ln, being triclinic, Pī , a ≈ 18.1, b ≈ 13.3, c ≈ 11 Ǻ, α ≈ 111.5, β ≈ 96.2, γ ≈ 109.2°, Z = 2 formula units, full structure determinations being recorded for Ln = La (conventional R 0.048 on |F| for No 6494 independent 'observed' [I > 3σ(I)] reflections at convergence), Ce (R 0.036 for No 8980) and Lu (R 0.046 for No 6791). A less well defined protonated series, with a 2:3 Cr/ Ln ratio, has also been characterized specifically for Ln = La [orthorhombic, Pbca , a 26.223(8), b 53.17(3), c 18.329(9) Ǻ, Z = 8; R 0.092 for No 5104], the lutetium analogue having a similar cell.

Reaction of Cp(OC)2Cr=S = Cr(CO)2Cp with Fe3(CO)12 affords an encapsulated μ6-O octahedral Fe4Cr2 cluster complex Cp2Cr2Fe4(CO)12(μ6-O), whose crystal structure is determined by X-ray diffraction analysis.
