Chloridobis{N-[(dimethyl-amino)dimethyl-silyl]-2,6-dimethyl-anilido-?N,N'}iron(III).

ABSTRACT: The title iron(III) compound, [Fe(C(12)H(21)N(2)Si)(2)Cl], is monomeric. The Fe atom is N,N'-chelated by the N-silylated anilide ligand. The two ligands around the Fe atom are arranged trans to each other. The Fe-N(amino) bond is longer than the Fe-N(anilide) bond by about 0.37?Å. The mol-ecule displays a pseudo-twofold rotation. The five-coordinate Fe atom demonstrates a highly distorted trigonal-bipyramidal geometry.

Project description:In the monomeric title titanium(III) compound, [Ti(C(12)H(21)N(2)Si)(2)Cl], the metal atom is surrounded by two N-silylated anilide ligands in an N,N''-chelating mode. The two ends of the N-Si-N chelating unit exhibit different affinity to the metal center. The Ti-N(amine) bond is longer than the Ti-N(anilide) bond by about 0.29?Å. The two ligands are arranged trans to each other and the mol-ecule demonstrates a pseudo-twofold rotation along the axis of the Ti-Cl bond. The five-coordinate Ti atom demonstrates a highly distorted trigonal-bipyramidal geometry.

Dichloridobis{N-[(dimethyl-amino)dimethyl-silyl]-2,6-dimethyl-anilido-κN,N'}zirconium(IV).

Project description:The monomeric title zirconium(IV) compound, [Zr(C(12)H(21)N(2)Si)(2)Cl(2)], was prepared by the metathetical reaction of [LiN(SiMe(2)NMe(2))(2,6-Me(2)C(6)H(3))](2) with zirconium tetra-chloride. The Zr(IV) atom is N,N'-chelated by the N-silylated anilido ligand. Along with two Cl atoms, the six-coordinated Zr(IV) atom demonstrates a highly distorted octa-hedral geometry. The two ligands around the Zr(IV) atom are arranged cis to each other and obey the C(2) symmetry operation. That means the asymmetric unit consists of only half of the mol-ecular compound and the complete mol-ecule is generated by a twofold axis. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal center. The Zr-N(amino) bond is longer than the Zr-N(anilido) bond.

Project description:The title compound, [Cu(2)(C(12)H(21)N(2)Si)(2)], is a binuclear Cu(I) complex. The dimeric mol-ecule has an inversion center located at the mid-point of the Cu-Cu bond [Cu-Cu = 2.7209?(7)?Å]. The bidentate ligand behaves in an N:N'-bridging mode, coordinating the metal atoms. The N-Cu-N unit is close to being linear [176.60?(8)°]. The two N atoms exhibit different affinities for the metal atom. The Cu-N(amino) bond is longer than the Cu-N(anilido) bond by 0.079?Å. The core of the mol-ecule, the [Cu-N-Si-N](2) eight-membered ring, adopts a chair configuration.

Chloridobis{2-[(dimethyl-amino)-meth-yl]phen-yl}anti-mony(III).

Project description:In the title compound, [Sb(C(9)H(12)N)(2)Cl], the Sb atom adopts a Ψ-trigonal-bipyramidal geometry. The two 2-[(dimethyl-amino)-methyl]-phenyl ligands are coordinated asymmetrically to the Sb atom. The carbon atoms of one of the ligands are disordered over sets of sites with equal occupancy, resulting in two conformational isomers in the crystal. The Sb-C and Sb-N distances in the ordered ligand are: 2.153 (4) and 3.326 (5) Å, respectively. The corresponding distances in the disordered ligand are: 2.103 (5)/2.188 (5) and 2.454 (3) Å, respectively. The structure displays intra-molecular C-H⋯Cl hydrogen bonding.

Chloridobis(dimethyl-glyoximato-?N,N')(4-methyl-pyridine-?N)cobalt(III) hemihydrate.

Project description:In the title complex, [Co(C(4)H(7)N(2)O(2))(2)Cl(C(6)H(7)N)]·0.5H(2)O, the central Co(III) ion, chelated by four N atoms of the two bidenate glyoximate ligands, exhibits a slightly distorted octa-hedral geometry. The axial positions are occupied by a chloride ion and the 4-methyl-pyridine N atom. Inter-molecular O-H?O hydrogen bonds link the mol-ecules in the crystal via the water mol-ecules, while the glyoximate ligands exhibit intra-molecular O-H?O hydrogen bonds.

Synthesis and crystal structures of tetra-meric [2-(4,4-dimethyl-2-oxazolin-2-yl)anilido]sodium and tris-[2-(4,4-dimethyl-2-oxazolin-2-yl)anilido]ytterbium(III).

Project description:Reaction of 2-(4,4-dimethyl-2-oxazolin-2-yl)aniline (H2-L1) with one equivalent of Na[N(SiMe3)2] in toluene afforded pale-yellow crystals of tetra-meric poly[bis-[?3-2-(4,4-dimethyl-2-oxazolin-2-yl)anilinido][?2-2-(4,4-dimethyl-2-oxa-zolin-2-yl)aniline]tetra-sodium(I)], [Na4(C11H13N2O)4] n or [Na4(H-L1)4] n (2), in excellent yield. Subsequent reaction of [Na4(H-L1)4] n (2) with 1.33 equivalents of anhydrous YbCl3 in a 50:50 mixture of toluene-THF afforded yellow crystals of tris-[2-(4,4-dimethyl-2-oxazolin-2-yl)anilinido]ytterbium(III), [Yb(C11H13N2O)3] or Yb(H-L1)3 (3) in moderate yield. Direct reaction of three equivalents of 2-(4',4'-dimethyl-2'-oxazolin-yl)aniline (H2-L1) with Yb[N(SiMe3)2]3 in toluene resulted in elimination of hexa-methyl-disilazane, HN(SiMe3)2, and produced Yb(H-L1)3 (3) in excellent yield. The structure of 2 consists of tetra-meric Na4(H-L1)4 subunits in which each Na+ cation is bound to two H-L1 bridging bidentate ligands and these subunits are connected into a polymeric chain by two of the four oxazoline O atoms bridging to Na+ cations in the adjacent tetra-mer. This results in two 4-coordinate and two 5-coordinate Na+ cations within each tetra-meric unit. The structure of 3 consists of a distorted octa-hedron where the bite angle of ligand L1 ranges between 74.72?(11) and 77.79?(11) degrees. The oxazoline (and anilide) N atoms occupy meridional sites such that for one ligand an anilide nitro-gen is trans to an oxazoline nitro-gen while for the other two oxazoline N atoms are trans to each other. This results in a significantly longer Yb-N(oxazoline) distance [2.468?(3)?Å] for the bond trans to the anilide compared to those for the oxazoline N atoms trans to one another [2.376?(3), 2.390?(3)?Å].

Chlorido{N-[(diethyl-amino)-dimethyl-sil-yl]anilido-?N}(N,N,N',N'-tetra-methyl-ethane-1,2-diamine-?(2) N,N')iron(II).

Project description:In the title iron(II) complex, [Fe(C12H21N2Si)Cl(C6H16N2)], the Fe(II) cation is coordinated by two N atoms from the tetramethylethane-1,2-diamine ligand [Fe-N = 2.191?(5) and 2.215?(4)?Å], one N atom from the N-[(diethyl-amino)-dimethyl-sil-yl]anilide ligand [Fe-N = 1.943?(4)?Å] and a chloride ligand [Fe-Cl = 2.2798?(16)?Å] in a distorted tetra-hedral geometry. The N-Si-N angle is 113.9?(3)°. The crystal packing exhibits no short inter-molecular contacts.

Bis(?(2)-?:?-2,4,6-trimethyl-benzonitrile)-bis-[(N-isopropyl-3,5-dimethyl-anilido)molybdenum(III)](Mo-Mo).

Project description:The title compound, [Mo(2)(C(11)H(16)N)(4)(C(10)H(11)N)(2)], is a dinuclear molybdenum complex with a formal metal-metal bond [Mo?Mo separation = 2.5946?(8)?Å], four anilide-type ligands and two bridging mesityl nitrile groups. There are two inversion symmetric mol-ecules in the unit cell (an inversion center is localized at the mid-point of the Mo-Mo bond), each with approximate non-crystallographic C(2h) symmetry. The mol-ecules contain disordered isopropyl and 3,5-C(6)H(3)Me(2) groups on different anilido ligands; the major component having an occupancy of 0.683?(7). The complex was obtained in low yield as the product from the reaction between the bridging pyrazine adduct of molybdenum tris--anilide ([?(2)-(C(4)H(4)N(2)){Mo(C(11)H(16)N)(3)}(2)]) and mesityl nitrile with a loss of one anilido ligand.

Chloridobis(dimethyl-glyoximato-?N,N')(ethyl pyridine-3-carboxyl-ate-?N)cobalt(III).

Project description:In the title compound, [Co(C(4)H(7)N(2)O(2))(2)Cl(C(8)H(9)NO(2))], which was prepared as a model complex of vitamin B(12), the Co(III) atom, which is linked to four N atoms of the pseudo-macrocyclic (dmgH)(2) ligand (dmgH is dimethyl-glyoximate) in the equatorial plane and one Cl(-) anion and one N atom of ethyl nicotinate in apical positions, displays an approximately octa-hedral coordination. The Co atom is 0.0187?(8)?Å out of the mean plane of the four equatorial N atoms. The structure has an O?H?O bridge, which is very common in cobaloxime derivatives, with O?H distances of 1.24?(2) and 1.25?(2)?Å.

Aqua-chloridobis[5-(2-pyrid-yl)-1H-tetra-zolato-?N]iron(III).

Project description:The title compound, [Fe(C(6)H(4)N(5))(2)Cl(H(2)O)], was synthesized by hydro-thermal reaction of FeCl(3) with 2-(1H-tetra-zol-5-yl)pyridine. The iron(III) metal centre exhibits a distorted octa-hedral coordination geometry provided by four N atoms from two bidentate organic ligands, one water O atom and one chloride anion. The pyridine and tetra-zole rings are nearly coplanar [dihedral angles = 4.32?(15) and 5.04?(14)°]. In the crystal structure, inter-molecular O-H?N hydrogen bonds link the complex mol-ecules into a two-dimensional network parallel to (100).
