{2,2'-[1,1'-(Ethane-1,2-diyldinitrilo)-diethyl-idyne]diphenolato}bis-(pyrrolidine)cobalt(III) perchlorate p-xylene hemisolvate.

ABSTRACT: In the mononuclear title complex, [Co(C(18)H(18)N(2)O(2))(C(4)H(9)N)(2)]ClO(4)·0.5C(8)H(10), the Co(III) ion has a slightly distorted octa-hedral coordination geometry. In the Me-salen ligand, the benzene rings are almost parallel, making a dihedral angle of 0.48?(13)°, but the torsion angle along the central C-C bond is 41.1?(2)°·The pyrrolidine rings are in slightly distorted chair conformations. The N atoms of the pyrrolidine axial ligands are involved in N-H?O hydrogen bonds with the perchlorate anions, and these hydrogen bonds connect the ionic species into infinite chains along the b axis. Some relatively short C-H?? inter-actions are also present in the crystal structure and C-H?O inter-actions occur. The guest solvent p-xylene mol-ecule lies on a special position at the inversion centre.

{4,4'-Dimeth-oxy-2,2'-[1,1'-(ethane-1,2-diyldinitrilo)diethyl-idyne]diphenolato}nickel(II) hemihydrate.

Project description:In the title complex, [Ni(C(20)H(22)N(2)O(4))]·0.5H(2)O, the Ni(II) ion is in a slightly distorted square-planar geometry involving an N(2)O(2) atom set of the tetra-dentate Schiff base ligand. The asymmetric unit contains one mol-ecule of the complex and half a water solvent mol-ecule. The solvent water mol-ecule lies on a crystallographic twofold rotation axis. An inter-molecular O-H⋯O hydrogen bond forms an R(2) (1)(4) ring motif involving a bifurcated hydrogen bond to the phenolate O atoms of the complex. In the crystal structure, mol-ecules are linked by π-π stacking inter-actions, with centroid-centroid distances in the range 3.5310 (11)-3.7905 (12) Å, forming extended chains along the b axis. In addition, there are Ni⋯Ni and Ni⋯N inter-actions [3.4404 (4)-4.1588 (4) and 3.383 (2)-3.756 (2) Å, respectively] which are shorter than the sum of the van der Waals radii of the relevant atoms. Further stabilization of the crystal structure is attained by weak inter-molecular C-H⋯O and C-H⋯π inter-actions.

Bis{μ-2,2'-[1,1'-(ethane-1,2-diyldinitrilo)diethyl-idyne]diphenolato}bis-[(benzoato-κO)manganese(III)] dihydrate.

Project description:The title compound, [Mn(2)(C(18)H(18)N(2)O(2))(2)(C(7)H(5)O(2))(2)]·2H(2)O, was synthesized by the reaction between manganese(II) benzoate and the Schiff base generated in situ by the condensation of ethane-1,2-diamine and o-hydroxy-aceto-phen-one. The Jahn-Teller-distorted manganese(III) ions of the centrosymmetric dimer are connected through phen-oxy bridges. Hydrogen-bonding inter-actions between the uncoord-in-ated C=O of the benzoate and uncoordinated water mol-ecules link the dimers into a chain running parallel to the c axis.

Project description:The title compound, [Mn(2)(C(18)H(18)N(2)O(2))(2)Cl(2)], was synthesized by the reaction between manganese(II) o-chloro-benzoate and the Schiff base generated in situ by the condensation of ethane-1,2-diamine and o-hydroxy-acetophenone. The centrosymmetric dimer contains two Jahn-Teller-distorted mangan-ese(III) ions, each in an octa-hedral geometry, connected through two phen-oxy bridges from two ligands.

{4,4',5,5'-Tetra-methyl-2,2'-[1,1'-(ethane-1,2-diyldinitrilo)diethyl-idyne]diphenolato}nickel(II)-methanol-chloro-form (1/1/1).

Project description:In the title compound, [Ni(C(22)H(26)N(2)O(2))]·CH(3)OH·CHCl(3), the Ni(II) ion is in a slightly distorted square-planar geometry involving an N(2)O(2) atom set of the tetra-dentate Schiff base ligand. The asymmetric unit contains one mol-ecule of the complex and one mol-ecule each of chloro-form and methanol. The methanol mol-ecule is hydrogen bonded to the phenolate O atoms. In the crystal structure, short inter-molecular distances between the centroids of six-membered chelate rings [3.7002?(9)?Å] indicate the presence of ?-? inter-actions, which link the mol-ecules into stacks along the a axis. In addition, there are Ni?Ni distances which are shorter than the sum of the van der Waals radii of two Ni atoms. The crystal structure is further stabilized by inter-molecular O-H?O and C-H?O hydrogen bonds, and weak inter-molecular C-H?? inter-actions linking mol-ecules into extended one-dimensional chains along the c axis.

Project description:The tetra-dentate dianion in the title complex hydrate, [Cu(C(23)H(28)N(2)O(4))]·H(2)O, provides the Cu(II) atom with a cis-N(2)O(2) donor set. There is a significant twist from a regular square-planar geometry with the dihedral angle formed between the two six-membered CuOC(3)N chelate rings being 32.14?(8)°. The water mol-ecule forms hydrogen bonds to each of the coordinating O atoms of a given complex mol-ecule. Supra-molecular layers in the bc plane are formed in the crystal packing through C-H?O and C-H?? inter-actions.

2,2'-[(E,E)-1,1'-(2,2-Dimethyl-propane-1,3-diyldinitrilo)diethyl-idyne]diphenol.

Project description:The title Schiff base, C(21)H(26)N(2)O(2), contains two intra-molecular O-H?N hydrogen bonds between the hydroxyl groups and the nearest imine N atoms, each leading to a six-membered ring. Weak C-H?O hydrogen bonds result in a ladder network running along the a axis. In addition, inter-molecular C-H?? inter-actions serve to stabilize the extended structure.

4,4',5,5'-Tetra-methyl-2,2'-[1,1'-(propane-1,3-diyldinitrilo)diethyl-idyne]diphenol.

Project description:The title Schiff base compound, C(23)H(30)N(2)O(2), has crystallographic twofold rotation symmetry. An intra-molecular O-H?N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The imino group is coplanar with the benzene ring. The two benzene rings are almost perpendicular to each other, making a dihedral angle of 87.38?(4)°. In the crystal structure, neighbouring mol-ecules are linked along the c axis by weak inter-molecular C-H?O hydrogen bonds and are further packed into columns along the b axis, forming sheets which are parallel to the bc plane.

Project description:In the cation of the title compound, [Mn(C(18)H(18)N(2)O(4))(H(2)O)(2)]ClO(4)·0.5C(12)H(24)O(6)·H(2)O, the Mn(III) ion is coordinated by two water O atoms, and two O atoms and two N atoms from the tetradentate 6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]di-phenolate ligand, completing a distorted octa-hedral geometry. One O atom of the 18-crown-6-ether is disordered over two positions with occupancies of 0.70?(2) and 0.30?(2).

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.
