[?-1,3-Bis(trimethyl-sil-yl)cyclo-penta-dien-yl]dichlorido[?-(trimethyl-sil-yl)cyclo-penta-dien-yl]titanium(IV).

Project description:In the title compound, [Ti(C(8)H(13)Si)(C(11)H(21)Si(2))Cl(2)], the Ti(IV) atom is bonded to two Cl atoms, one 1,3-bis-(trimethyl-sil-yl)cyclo-penta-dienyl (Si(2)Cp) and one (trimethyl-sil-yl)cyclo-penta-dienyl ring (SiCp). The Si(2)Cp centroid-titanium distance is 2.0763?(10)?Å and the SiCp centroid-titanium distance is 2.0793?(10)?Å. The angle subtended at the Ti atom by the centroids of both cyclo-penta-dienyl rings is 131.22?(4)° and the Cl-Ti-Cl angle is 94.14?(2)°.

Tri-?-ethanethiol-ato-bis-{[?-1,2,3,4-tetra-methyl-5-(trimethyl-silyl)cyclo-penta-dien-yl]iron(II,III)}(Fe-Fe).

Project description:The title complex, [Fe(2)(C(2)H(5)S)(3)(C(12)H(21)Si)(2)], has an unusual Fe(2)S(3) core. The two 1,2,3,4-tetra-methyl-5-(trimethyl-silyl)cyclo-penta-dienyl (Cp') ligands coordinate to the Fe atoms with their C(5) planes perpendicular [dihedral angles = 88.23?(7) and 88.55?(7)°] to the Fe-Fe vector, building two Cp'Fe subunits. These two subunits are bridged by three thiol-ate ligands. There are no significant differences in the coordination geometries between the two Fe atoms. The short Fe-Fe distance of 2.7842?(5)?Å is clear evidence of an inter-metallic bond. Such a diiron-sulfur structure might act as a model of active sites in some metalloproteins.

N,N-Bis(diphenyl-phosphan-yl)cyclo--penta-namine.

Project description:The coordination around the N atom in the title compound, C(29)H(29)NP(2), shows an almost planar geometry, defined by the attached P and C atoms, in order to accomodate the steric bulk of the phenyl rings. The distortion of the trigonal-pyramidal geometry of the N atom is illustrated by the bond angles ranging between 115.22?(12) and 121.76?(9)°. The P atoms present a pyramidal environment with bond angles ranging from 100.62?(9) to 104.71?(8)°. One of the C atoms in the cyclo-pentyl ring displays a 0.822?(4):0.178?(4) positional disorder. Within the crystal structure, intra-molecular C-H?P hydrogen bonds together with inter- and intra-molecular C-H?? inter-actions link the mol-ecules into a supra-molecular two-dimensional network.

(2E,5E)-2,5-Bis(3,4,5-trimethoxy-benzyl-idene)cyclo-penta-none.

Project description:The title compound, C(25)H(28)O(7), was prepared by the base-catalysed reaction of 3,4,5-trimethoxy-benzaldehyde with cyclo-penta-none. The mol-ecule has crystallographic twofold rotation symmetry and adopts an E-configuration about the central olefinic bonds. The two benzene rings and the central cyclo-penta-none ring are almost coplanar [dihedral angle = 4.7?(2)°].

[μ-Bis(trimethyl-silyl)amido]bis-[μ-N,N-dimethyl-N',N''-bis-(trimethyl-silyl)guanidinato]-triangulo-tricopper(I).

Project description:The title compound, [Cu(3)(C(6)H(18)NSi(2))(C(9)H(24)N(3)Si(2))(2)], is a trinuclear Cu(I) complex. A crystallographic twofold axis passes through one Cu(I) atom and the N atom of the bis-(trimethyl-silyl)amide ligand that bridges between the other two Cu(I) atoms. The Cu-Cu bonds bridged by the guanadinate ligands [2.7913 (9) Å] are slightly longer than the Cu-Cu bond bridged by the bis-(trimethyl-silyl)amide ligand [2.6405 (11) Å].

Project description:In the title compound, [Fe(C(10)H(15))Cl(C(26)H(24)P(2))]·CH(2)Cl(2), the Fe(II) atom is coordinated by two P atoms from a 1,2-bis-(diphenyl-phosphino)ethane ligand [Fe-P = 2.2130?(7) and 2.2231?(7)?Å], a chloride anion [Fe-Cl = 2.3329?(7)?Å] and a penta-methyl-cyclo-penta-dienyl (Cp*) ligand [Fe-centroid(Cp*) = 1.732?(3)?Å] in a typical piano-stool geometry. In the crystal structure, the complex and solvent mol-ecules are paired via weak C-H?Cl inter-actions.

Project description:In the title compound, [Mo(C(5)H(5))(CO)(2)(C(3)H(9)P)(2)]CF(3)SO(3), the cationic complex displays a classical four-legged piano-stool square-pyramidal geometry with a trans configuration of the basal ligands around the Mo atom.

The average Mo-P bond length of the two trans PMe(3) ligands is 2.474 (5) Å and the Mo-Cp centroid distance is 2.003 (2) Å.
