[2,2'-(2,6,9,13-Tetra-azatetra-decane-1,14-di-yl)diphenolato]iron(III) iodide.

ABSTRACT: The title Fe(III) complex, [Fe(C(22)H(32)N(4)O(2))]I, contains a six-coordinate FeN(4)O(2) cation in which the ligand is a reduced Schiff base resulting from the NaBH(4) reduction of the condensation product between salicylaldehyde and 1,5,8,12-tetra-azadodecane. In spite of the increased flexibility of the saturated backbone of the ligand compared to the Schiff base from which it was synthesized, the complex adopts a cis-FeN(4)O(2) conformation for the phenolic O-atom donors, which contrasts with the trans conformation adopted by the analogous ClO(4) (-) salt [Yisgedu et al. (2009 ?). J. Chem. Crystallogr.39, 315-319]. In addition to extensive N-H?I hydrogen bonding between the amine H atoms and the anion there is a weak C-H?I inter-action.

Aqua-{4,4',6,6'-tetra-fluoro-2,2'-[(piperazine-1,4-di-yl)dimethyl-ene]diphenolato}copper(II).

Project description:In the title compound, [Cu(C(18)H(16)F(4)N(2)O(2))(H(2)O)], the Cu(II) atom shows a distorted square-pyramidal coordination geometry with the N,N',O,O'-tetra-dentate piperazine-diphenolate ligand forming the basal plane. The apical site is occupied by the O atom of a coordinated water mol-ecule. Neighbouring complexes are associated through inter-molecular O-H?O and O-H?F hydrogen bonds between the water mol-ecule and a phenolate O atom or an F atom from an adjacent ligand, respectively, forming a centrosymmetric dimer. Dimers are linked by additional inter-molecular C-H?O and C-H?F hydrogen bonds, giving infinite chains propagating along the a axis.

Crystal structure of chlorido-{5,10,15,20-tetra-kis-[2-(2,2-di-methyl-propanamido)-phen-yl]porphyrinato-?(4) N}iron(III).

Project description:The title compound, [Fe(C64H64N8O4)Cl], is a five-coordinate square-pyramidal porphyrin complex with a chloride ion in the axial position, being coordinated from the protected side of the porphyrin; the Fe(III) atom is displaced by 0.474?(5)?Å from the 24-atom mean plane of the porphyrin core towards the chloride. The porphyrin moiety is a 'picket-fence' 5,10,15,20-tetra-kis-[2-(2,2-di-methyl-propanamido)-phen-yl]porph-yrinate (por) group. The Fe-Cl bond length is 2.221?(2)?Å and the Fe-N(por) bond lengths are in the range 2.043?(5)-2.063?(5)?Å. The supra-molecular architecture of the crystal is sustained by C-H?O inter-actions between the pyrrolic and phenyl H atoms of one mol-ecule and the carbonyl O atoms of the 2,2-di-methyl-propanamido groups of adjacent mol-ecules. The methyl groups of three of the four tert-butyl substituents exhibited rotational disorder over two positions. The investigated crystal was twinned by a twofold rotation about the (001) axis with a refined twin ratio of 0.4086?(16).

Project description:In the title mononuclear complex, [La(NO(3))(3)(C(22)H(26)N(2)O(4))]·CH(3)OH, the La(III) ion is coordinated by three bidentate nitrate counter-ions and one zwitterionic 6,6'-dimeth-oxy-2,2'-[(cyclo-hexane-1,2- di-yl)bis-(nitriliomethyl-idyne)]diphenolate ligand through two phenolate and two meth-oxy O atoms, while the protonated N atoms remain uncoordinated. H atoms located on the two N atoms are involved in intra-molecular hydrogen bonds with the deprotonated phenol O atoms, indicating that proton migration occurs during the lanthanum complexation.

{2,2'-[(2,2-Dimethyl-propane-1,3-di-yl)-bis-(nitrilo-methyl-idyne)]-diphenolato}-dioxidomolybdenum(VI).

Project description:In the structure of the title compound, [Mo(C(19)H(20)N(2)O(2))O(2)], the Mo atom exhibits oxidation state +VI and is surrounded by two O atoms and the tetra-dentate Schiff base ligand 2,2'-[(2,2-dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]diphenolate in a distorted octa-hedral configuration.

Project description:In the title compound, [Cr(2)Ni(C(16)H(14)N(2)O(2))(2)(CN)(4)(C(10)H(24)N(4))]·2CH(3)OH, each [Cr(salen)(CN)(2)] unit {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate} acts as a monodentate ligand through one of its two cyanide groups N bound to a central [Ni(cyclam)](2+) core (cyclam is 1,4,8,11-tetra-azacyclo-tetra-deca-ne). Each Cr(III) ion is coordinated by two N and two O atoms from a salen ligand situated in the equatorial plane with two trans cyanide C atoms, yielding a distorted octa-hedral coordination geometry. The Ni(II) atom lies on an inversion center and is octa-hedrally coordinated by a cyclam ligand lying in the equatorial plane and by two cyanide N atoms. The asymmetric unit contains one half of the complex mol-ecule and a methanol solvent mol-ecule. In the crystal structure, the complex mol-ecule is linked to the methanol solvent mol-ecules via O-H?O and N-H?O hydrogen bonds. Individual complex mol-ecules are linked by C-H?N hydrogen bonds, forming chains along b.

In the crystal structure, mol-ecules are stacked approximately along the b-axis direction. The O atom and three H atoms of the solvent molecule are disordered over two positions; the site occupancy factors are ca 0.8 and 0.2.
