1-(Bromo-mercurio)ferrocene.

ABSTRACT: The asymmetric unit of the title compound, [Fe(C5H5)(C5H4BrHg)], contains two independent mol-ecules, A and B, in which the Hg-C bond lengths are 2.045?(6) and 2.046?(6)?Å, the Hg-Br bond lengths are 2.4511?(9) and 2.4562?(7)?Å, and the C-Hg-Br angles are 176.42?(17) and 177.32?(17)°. The two cyclo-penta-dienyl rings of mol-ecule A are eclipsed, while those of mol-ecule B are almost staggered. The HgBr groups are connected by inter-molecular Hg?Br contacts of 3.3142?(9)-3.4895?(11)?Å, forming layers parallel to (001). These layers contain both four-membered (HgBr)2 and eight-membered (HgBr)4 rings. Ferrocene-ferrocene C-H?? contacts connect the mol-ecular layers along the c-axis direction.

The asymmetric unit of the title compound, [Fe(C5H5)(C5H4BrHg)], contains two independent mol-ecules, A and B, in which the Hg-C bond lengths are 2.045 (6) and 2.046 (6) Å, the Hg-Br bond lengths are 2.4511 (9) and 2.4562 (7) Å, and the C-Hg-Br angles are 176.42 (17) and 177.32 (17)°. The two cyclo-penta-dienyl rings of mol-ecule A are eclipsed, while those of mol-ecule B are almost staggered.

(2-Bromo-acet-yl)ferrocene.

Project description:In the title mol-ecule, [Fe(C(5)H(5))(C(7)H(6)BrO)], the C atoms of the substituted ring have disparate Fe-C bond lengths compared with the unsubstituted ring. In the bromo-acetyl residue, the Br and O atoms are co-planar [the O-C-C-Br torsion angle is 5.7?(4)°] and are syn to each other. Helical supra-molecular chains along the b axis are formed in the crystal structure mediated by C-H?O contacts; the carbonyl-O atom is bifurcated. The chains are linked into layers by C-H??(unsubstituted ring) inter-actions that stack along the a-axis direction.

1-(4-Bromo-phen-yl)ferrocene.

Project description:In the title compound, [Fe(C(5)H(5))(C(11)H(8)Br)], the distance of the Fe atom from the centroids of the unsubstituted and substituted cyclo-penta-dienyl (Cp) rings is 1.644 (1) and 1.643 (1) Å, respectively. The ferrocenyl moiety deviates from an eclipsed geometry, with marginally tilted Cp rings and an inter-planar angle between the Cp and benzene rings of 13.0 (4)°. The crystal structure is stabilized by C-H⋯π inter-actions between a cyclo-penta-dienyl H atom and the cyclo-penta-dienyl ring of a neighbouring mol-ecule.

1-Bromo-1'-(diphenyl-thio-phosphor-yl)-ferrocene.

Project description:The title compound, [Fe(C(5)H(4)Br)(C(17)H(14)PS)], crystallizes with two practically undistiguishable mol-ecules in the asymmetric unit, which are related by a non-space-group inversion. The ferrocene-1,1'-diyl units exhibit a regular geometry with negligible tilting and balanced Fe-ring centroid distances, and with the attached substituents assuming conformations close to ideal synclinal eclipsed.

(2,2-Dichloro-vinyl)ferrocene.

Project description:The title compound, [Fe(C(5)H(5))(C(7)H(5)Cl(2))], represents a versatile building block for the preparation of ?-conjugated redox-active compounds or polymetallic organometallic systems due to the presence of the electrochemically active ferrocenyl unit. It is therefore a potential starting material for the preperation of the corresponding alkyne. In the crystal, the alkenyl unit and the cyclo-penta-dienide ring are almost parallel, with an angle between the best planes of only 10.6?(4)°.

(6-Chloropyridazin-3-yl)ferrocene.

Project description:The asymmetric unit of the title compound, [Fe(C5H5)(C9H6ClN2)], contains two independent mol-ecules in which the cyclo-penta-dienyl rings are almost parallel, making dihedral angles of 2.16?(4) and 2.71?(5), and the dihedral angles between the pyridazinyl and substituted cyclo-penta-dienyl rings are 9.65?(5) and 11.53?(8)°. In the crystal, mol-ecules are linked by C-H?N hydrogen bonds into chains along the c-axis direction.

Dibenzyl ferrocene-1,1'-dicarboxyl-ate.

Project description:In the title compound, [Fe(C(13)H(11)O(2))(2)], there are markedly different orientations of the two phenyl-meth-oxy-carbonyl substituents [O-C-C-C torsion angles = 84.5?(3) and 139.6?(2)°]. These orientations are mediated by a number of inter-molecular C-H?O inter-actions, which result in a one-dimensional hydrogen-bonded network of mol-ecules.

Ferrocene-1-carbaldehyde thio-semi-carbazone.

Project description:The asymmetric unit of the title compound, [Fe(C(5)H(5))(C(7)H(8)N(3)S)], consists of two crystallographically independent mol-ecules, A and B. The cyclo-penta-dienyl (Cp) rings in both mol-ecules adopt an eclipsed conformation and are parallel to each other, forming dihedral angles of 2.5?(3) and 1.1?(3)°, respectively. The mean plane of the semicarbazone group is coplanar with the attached Cp ring in mol-ecule A, whereas it is twisted away in mol-ecule B. In the crystal structure, inter-molecular N-H?S hydrogen bonds link the mol-ecules into two-dimensional planes parallel to the ab plane. The structure is further consolidated by C-H?? inter-actions.

(1-Naphthyl-imino-meth-yl)ferrocene.

Project description:In the title mol-ecule, [Fe(C(5)H(5))(C(16)H(12)N)], the cyclo-penta-dienyl rings are approximately eclipsed and the inter-planar angle is 0.8?(7)°. The Fe atom is slightly closer to the substituted cyclo-penta-dienyl ring, with an Fe?centroid distance of 1.639?(2)?Å, compared with 1.645?(2)?Å for the unsubstituted ring.

The angle formed by the C=N double bond and the naphthal-ene ring system is 47.1?(1)°. The C-N=C-C torsion angle is 177.32?(5)°.

New 1,1'-Ferrocene Bis(sulfonyl) Reagents.

Project description:Several new 1,1'-bis(sulfonyl)ferrocenes designed for the synthesis of sulfonamide linked biological conjugates have been prepared. 1,1'-Bis(sulfonylbromide)ferrocene can be produced from the corresponding sulfonylchloride via a bis(sulfonylhydrazide) intermediate. Bis(sulfonyl-N-hydroxybenzotriazole)ferrocene can also be synthesized from the sulfonyl chloride, and reaction of glycine methyl ester with the sulfonyl chloride affords a [3]ferrocenophane complex. All new compounds have been structurally characterized by X-ray crystallography.
