چکیده
The title salt, [K(C(12)H(24)O(6))][Fe(C(8)H(12))(C(10)H(8))], is the only known naphthalene complex containing iron in a formally negative oxidation state. Each (naphthalene)(1,5-cod)ferrate(-I) anion is in contact with one (18-crown-6)potassium cation via K⋯C contacts to the outer four carbon atoms of the naphthalene ligand (cod = 1,5-cyclo-octa-diene, 18-crown-6 = 1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne). When using the midpoints of the coordinating olefin bonds, the overall geometry of the coordination sphere around iron can be best described as distorted tetra-hedral. The naphthalene fold angle between the plane of the iron-coordinating butadiene unit and the plane containing the exo-benzene moiety is 19.2 (1)°.

The reaction of (η(3)-all-yl)[(1,2,5,6-η)-cyclo-octa-1,5-diene]rhodium(I) with tris-(2,4-di-tert-butyl-phen-yl)phosphite in toluene produces the title compound, [Rh(C(42)H(62)O(3)P)(C(8)H(12))]·C(7)H(8), by spontaneous metallation at one of the nonsubstituted phenyl ortho-C atoms of the phosphite mol-ecule. The coordination geometry at the Rh(I) ion is distorted square-planar. The toluene solve...

In the mononuclear title complex, [Pt(C(7)H(7))(2)(C(8)H(12))], the Pt(II) ion exhibits a square-planar coordination geometry defined by two methyl-phenyl ligands and the mid-points of the two π-coordinated double bonds of cyclo-octa-1,5-diene. The two methyl-phenyl groups have a cis relationship with a C-Pt-C bond angle of 88.54 (18)° and a dihedral angle between the mean planes of the benzene...

The title compound, [Rh(C(8)H(12))(C(18)H(36)P(2))]BF(4), exhibits a rhodium(I) complex cation with a bidentate bis-phosphine ligand and a bidentate η(2),η(2)-coordinated cyclo-octa-1,5-diene ligand. The ligands form a slightly distorted square-planar coordination environment for the Rh(I) atom. An intra-molecular P-Rh-P bite angle of 83.91 (2)° is observed. The dihedral angle between the P-Rh-...

A reaction between [(COD)IrCl]2 (COD is cyclo-octa-1,5-diene), HCl and indene failed to provide the hoped for chlorido-indenyliridium dimer, but instead produced the title compound, [IrCl3(CH3CN)(C8H12)], which is an octa-hedral complex of iridium(III) with a chelating cyclo-octa-1,5-diene ligand, three chloride ligands in a fac arrangement, and one aceto-nitrile ligand. Attempts to devise a ra...

In the title complex, [Pt(C(6)H(11))Cl(C(8)H(12))], the Pt(II) ion lies in a distorted square-planar environment defined by the Cl and cyclo-hexyl C atoms and the mid-points of the two π-coordinated double bonds of cyclo-octa-1,5-diene. As a result of the different trans influences of the Cl atom and the cyclo-hexyl group, the Pt-C bonds trans to the cyclo-hexyl group are longer than those tran...
