Trichloridotris{N-[phen­yl(pyridin-2-yl)­methyl­idene]hydroxyl­amine-κ²N,N′}samarium(III)

The Sm^III ion in the title compound, [SmCl₃(C₁₂H₁₀N₂O)₃], shows a coordination number of nine with a slightly distorted tricapped trigonal prismatic geometry based on a Cl₃N₆ donor set. The mol­ecular structure is stabilized by three intra­molecular O—H...Cl hydrogen bonds.

Bis[2-(benzyl­imino­meth­yl)pyrrol-1-ido-κ²N,N′]bis­(dimethyl­amido-κN)titanium(IV)

The mononuclear title complex, [Ti(C₂H₆N)₂(C₁₂H₁₁N₂)₂], was synthesized by the reaction of 1-phenyl-N-[(pyrrol-2-yl)methyl­idene]methanamine with Ti(NMe₂)₄. The Ti^IV atom is coordinated in a distorted octa­hedral geometry by four N atoms from two derivatized methanamine ligands and two N atoms from two dimethyl­amide ions. The dihedral angles between the pyrrole and phenyl rings in the bidentate ligands are 62.36 (9) and 78.32 (8)°. In the crystal, a weak π–π stacking inter­action [centroid–centroid distance = 3.864 (2) Å] involving centrosymmetrically related mol­ecules is observed.

Bis{2-[(4-chloro­phen­yl)imino­meth­yl]pyrrol-1-ido-κ²N,N′}bis­(dimethyl­amido-κN)titanium(IV) toluene monosolvate

The mononuclear title compound, [Ti(C₁₁H₈ClN₂)₂(C₂H₆N)₂]·C₇H₈, was synthesized by the reaction of N-(4-chloro­phen­yl)-2-pyrrolylcarbaldimine with Ti(C₂H₆N)₄. The Ti^IV ion is situated on a twofold rotation axis and displays a distorted octa­hedral geometry defined by four N atoms from two 2-[(4-chloro­phen­yl)imino­meth­yl]pyrrol-1-ide ligands and two N atoms from two dimethyl­amine ligands. The Ti—N_pyrrole bond length [2.1041 (19) Å] is longer than the Ti—N_{dimethyl­amine} bond length [1.9013 (19) Å]; the imine N atom exhibits the longest Ti—N bond [2.3152 (17) Å]. The toluene solvent mol­ecule is located on a twofold rotation axis running through the C atom of the methyl group. Consequently, the H atoms of the latter are rotationally disordered. The compound contains no markable hydrogen-bonding inter­actions.
