catena-Poly[[[{5,5'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}manganese(III)]-?-acetato] methanol monosolvate].

Project description:The title Mn(III) compound, {[Mn(C(18)H(18)N(2)O(4))(CH(3)COO)]·CH(3)OH}(n), was synthesized by a reaction between mangan-ese(II) acetate and ethyl-enebis(4-meth-oxy-salicylaldimine). The structure is made up of bis-(4-meth-oxy-salicyldene)ethyl-enediaminatomanganese(III) units bridged by acetate groups, with Mn-N = 1.9786?(9), Mn-O = 1.8784?(10) and Mn-O(acetate) = 2.056?(9) and 2.2571?(9)?Å, forming a one dimensional polymer (-Mn-acetate-Mn-acetate-) along [100]. The Mn(III) atom is in a Jahn-Teller-distorted octa-hedral environment with cis angles ranging from 81.87?(4) to 96.53?(4)° and trans angles ranging from 166.11?(3) to 173.93?(3)°. The methanol solvent mol-ecule is hydrogen bonded to the phenolate O atom. In addition to this classical hydrogen bond, there are weak C-H?O inter-actions. The structure was determined from a crystal twinned by pseudo-merohedry.

Ethyl-enediammonium tetra-kis({2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}nickel(II)) bis-(perchlorate) dimethyl-formamide monosolvate.

Project description:The title compound, (C(2)H(10)N(2))[Ni(C(16)H(14)N(2)O(2))](4)(ClO(4))(2)·C(3)H(7)NO, crystallizes with four Ni(salen) mol-ecules {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate}, one ethyl-enediammonium cation (actually two half-cations, each located on a center of inversion), two perchlorate anions and one dimethyl-formamide solvent mol-ecule in the asymmetric unit. Each Ni(II) cation in the Ni(salen) complex is four-coordinated by two imine N atoms and two phenolate O atoms from the tetra-dentate ligand. The Ni(salen) units form parallel slipped stacks with Ni?Ni separations of 3.4541?(4) and 3.6442?(6)?Å. The crystal packing is stabilized by inter-molecular hydrogen bonds between the ammonium H atoms and the perchlorate and salen O atoms, which generate a three-dimensional structure.

Aqua-{6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}methano-lmanganese(III)) perchlorate hemihydrate.

Project description:The asymmetric unit of the title compound, [Mn(C(18)H(18)N(2)O(4))(CH(3)OH)(H(2)O)]ClO(4)·0.5H(2)O, contains two complex cations and two perchlorate anions, one of which is disordered over two positions in a 0.767?(8):0.233?(8) ratio. The Mn(III) atoms are in distorted octa-hedral environments. In addition to the equatorial tetra-dentate salicylaldimine ligand, each Mn is axially coordinated by both a methanol and a water mol-ecule. The complex is a dimer held together by multiple strong and weak hydrogen-bonding inter-actions between the coordinated water mol-ecule on one monomer with all the phenolic and meth-oxy O atoms on the other monomer. In addition, the two perchlorate anions are linked by hydrogen bonds to the two methanol mol-ecules coordinated to each Mn center. The Mn-O phenolic bond distances range from 1.868?(2) to 1.882?(2)?Å while the Mn-N distances range from 1.978?(2) to 1.981?(2)?Å. Mn-O distances for the axial water and methanol ligands are longer at 2.226?(2)/2.257?(2) and 2.313?(2)/2.324?(2)?Å, reflecting the usual Jahn-Teller distortion as found in Mn(III) complexes.

Project description:The title compound, [Zn(C(19)H(13)N(3)O(2))], has been synthesized by the reaction of Zn(ClO(4))(2)·6H(2)O and the tetra-dentate Schiff base ligand 2,2'-[pyridine-3,4-diylbis(nitrilo-methyl-idyne)]diphenol (L). The coordination geometry of the Zn(II) ion is slightly distorted square-planar, formed by two N atoms and two O atoms from the L ligand.

Bis{?-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}dinickel(II).

Project description:The asymmetric unit of the title compound, [Ni(2)(C(16)H(14)N(2)O(2))(2)], contains an Ni(II) cation which is coordinated by two imine N atoms and by two phenolate O atoms of the salen ligand {salen = N,N'-bis-(salicyl-idene)ethane-1,2-diamine or 2,2'-[ethane-1,2-diyl-bis(nitrilo-methyl-idyne)]diphenol}, leading to a distorted square-planar conformation. When a secondary Ni-O inter-action > 2.41?Å to the neighbouring phenolate O atom is considered, two mol-ecules are linked into a centrosymmetric dimer with an overall square-pyramidal coordination for the Ni(II) cation. Weak ?-? inter-actions with a shortest interplanar distance of 3.704?Å help to stabilize the crystal structure.

Investigation of nitro-nitrito photoisomerization: crystal structures of trans-{2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}(pyridine/4-methyl-pyridine)-nitro-cobalt(III).

Project description:The reaction cavities of the nitro groups in the title compounds, trans-{2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato-?4 O,N,N',O'}(nitro-?N)(pyridine-?N)cobalt(III), [Co(C16H14N2O2)(NO2)(C5H5N)], (I), and trans-{2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato-?4 O,N,N',O'}(4-methyl-pyridine-?N)(nitro-?N)cobalt(III), [Co(C16H14N2O2)(NO2)(C6H7N)], (II), have been investigated to reveal that the inter-molecular CMe-H?O(nitro) contacts in (II) are unfeasible for the nitro-nitrito photochemical linkage isomerization process. In (I), there are two independent complexes showing similar conformations, and the central five-membered chelate ring of the tetra-dentate salen ligand adopts the same absolute configuration. This is the result of pseudo-spontaneous resolution, since the configuration of the five-membered chelate ring may frequently be reversed in solution. In the crystals of (I) and (II), the mol-ecules are linked into three-dimensional networks by C-H?O hydrogen bonds.

Project description:In the title compound, [Cu(C(16)H(12)Br(2)N(2)O(2))], the Cu(II) atom is coordinated in a slightly distorted square-planar geometry by two O and two N atoms of the tetra-dentate dianionic 4,4'-dibromo-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphen-olate Schiff base ligand.

Acetato(aqua){6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenolato}cobalt(III) methanol disolvate.

Project description:In the title complex, [Co(C(18)H(18)N(2)O(4))(C(2)H(3)O(2))(H(2)O)]·2CH(3)OH, the Co(III) atom is hexa-coordinated by water and acetate groups in the axial positions and by the tetra-dentate Schiff base occupying equatorial positions. These axial bonds are longer than the equatorial bonds to the tetra-dentate Schiff base. Two mol-ecules form a dimer through strong hydrogen bonds from the coordinated water of one mol-ecule to the meth-oxy O atoms of an adjoining mol-ecule. There is extensive intra- and inter-molecular O-H?O hydrogen bonding between the coordinated water and acetate ligands and the methanol solvent mol-ecules. In addition, there are weak inter-molecular C-H?O inter-actions, which link the mol-ecules into a three-dimensional array.

Project description:In title complex, [Co(C(28)H(22)N(2)O(2))(C(5)H(5)N)(2)]ClO(4)·1.5H(2)O, the Co(III) ion is in a slightly distorted octa-hedral coordination environment with the pyridine ligands in a trans arrangement. In addition to the cation and anion, the asymmetric unit also contains three half-occupancy solvent water mol-ecules and all components are connected via inter-molecular O-H?O hydrogen bonds.

The four-coordinate Zn(II) ion has a distorted square-planar coordination and is N(2)O(2)-chelated by the Schiff base ligand. The Zn(II) ion and solvent water mol-ecule are located on a twofold rotation axis. The structure displays inter-molecular O-H?O hydrogen bonding.
