Bis(?-6-meth-oxy-2-{[(3-oxidoprop-yl)imino]-meth-yl}phenolato)nickel(II) methanol monosolvate.

ABSTRACT: The mol-ecular structure of the title complex, [Ni2(C11H13NO3)2]·CH3OH, contains two Ni(II) atoms and two doubly deprotonated 6-meth-oxy-2-{[(3-oxidoprop-yl)imino]-meth-yl}phenolate ligands. The Ni(II) atoms are each four-coordinated in a distorted square-planar geometry by three O atoms and one N atom derived from the phenolate ligands. The solvent mol-ecule is linked to the complex mol-ecule by two O-H?O hydrogen bonds.

Project description:In the title compound, [Ni(C(12)H(16)NO(5))(2)]·2H(2)O, the Ni(II) atom is coordinated by four O atoms and two N atoms from the two 6-meth-oxy-2-{[tris-(hydroxy-meth-yl)meth-yl]imino-meth-yl}phenolate ligands in a distorted octa-hedral coordination geometry.

Crystal structure of (2-{[(8-aminona-phthalen-1-yl)imino]-meth-yl}-4,6-di-tert-butyl-phenolato-κ3N,N',O)bromido-nickel(II).

Project description:The title compound, [NiBr(C25H29N2O)], contains an NiII atom with a slightly distorted square-planar coordination environment defined by one O and two N atoms from the 2-{[(8-aminona-phthalen-1-yl)imino]-meth-yl}-4,6-di-tert-butyl-phenolate ligand and a bromide anion. The Ni-O and Ni-N bond lengths are slightly longer than those observed in the phenyl backbone counterpart, which can be attributed to the larger steric hindrance of the naphthyl group in the structure of the title compound. The mol-ecule as a whole is substanti-ally distorted, with both the planar naphthalene-1,8-di-amine and imino-meth-yl-phenolate substitutents rotated against the NiN2OBr plane by 38.92 (7) and 37.22 (8)°, respectively, giving the mol-ecule a twisted appearance. N-H⋯Br hydrogen bonds and N-H⋯C(π) contacts connect the mol-ecules into dimers, and additional C-H⋯Br contacts, C-H⋯π inter-actions, and an offset stacking inter-action between naphthyl units inter-connect these dimers into a three-dimensional network.

Bis{2-[(E)-(4-fluoro-benz-yl)imino-meth-yl]-6-meth-oxy-phenolato-?N,O}nickel(II).

Project description:In the title compound, [Ni(C(15)H(13)FNO(2))(2)], the Ni(II) atom is tetra-coordinated by two N atoms and two O atoms from two 2-[(4-fluoro-benz-yl)imino-meth-yl]-6-meth-oxy-phenolate ligands in a square-planar geometry. The two N atoms and two O atoms around the Ni(II) atom are trans to each other, as the Ni(II) atom lies on an inversion centre. In the fluoro-phenyl group, five C atoms and an F atom are disordered over two sets of positions of equal occupancy. In the crystal, the complex mol-ecules are linked via inter-molecular C-H?F hydrogen bonds, forming chains along [001].

Tris{2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato-?O,O'}tris-(thio-cyanato-?N)praseodymium(III) monohydrate.

Project description:The asymmetric unit of title compound, [Pr(NCS)(3)(C(15)H(15)NO(2))(3)]·H(2)O, consists of three Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)imino-meth-yl]phenol (HL) ligands, three independent thio-cyanate anions and an uncoordinated water mol-ecule.

{rac-5-[Meth-oxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II).

Project description:The title compound, [Ni(C(40)H(28)N(4)O)], was obtained from a Grignard reaction of the respective formyl-porphyrin to yield {5-[hy-droxy(phen-yl)meth-yl]-10,20-diphenyl-porphyrinato}nickel(II), followed by crystallization from methyl-ene chloride/methanol. The mol-ecule exhibits a ruffled macrocycle with an average deviation of the 24 macrocycle atoms from their least-squares plane (?24) of 0.26?Å and an average Ni-N bond length of 1.931?(2)?Å. In line with the asymmetrical substituent pattern, the degree of distortion is slightly larger at point of attachment of the meth-oxy(phen-yl)methyl residue than at the unsubstituted meso position. The meth-oxy group attached to the chiral C atom is disordered in a 0.534?(4):0.466?(4) ratio.

(Methanol-?O)bis-{2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato-?O,O'}tris-(nitrato-?O,O')lanthanum(III).

Project description:The asymmetric unit of title compound, [La(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], consists of two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato (HL) ligands, three independent nitrate anions and one methanol mol-ecule coordinated to La(III).

Three bidentate nitrate anions coordinate to the La(III) ion, while two HL ligands chelate the metal center with O atoms from the phenolate and meth-oxy groups. The HL ligands are zwitterionic, with protonated imine N atoms. The coordination sphere is completed by one methanol mol-ecule. The protonated imine N atoms are involved in intra-molecular N-H?O hydrogen bonds with the phen-oxy groups and nitrate ligands. One O atom of one nitrate group is disordered over two sites of equal occupancy.

Bis{6-meth-oxy-2-[(4-methyl-phen-yl)iminiometh-yl]phenolate-?O,O'}tris-(nitrato-?O,O')holmium(III) mono-hydrate.

Project description:The crystal structure of the title compound, [Ho(NO(3))(3)(C(15)H(15)NO(2))(2)]·H(2)O, contains two Schiff base 6-meth-oxy-2-[(4-methyl-phen-yl)iminiometh-yl]phenolate (L) ligands, three independent nitrate ions that chelate to the Ho(III) ion with O atoms and a hydrate water mol-ecule. The coordination environment of the Ho(III) ion is ten-coordinate. The L ligands chelate with a strong Ho-O(phenolate) bond and weaker Ho-O(meth-oxy) contacts. The latter can be inter-preted as the apices of the bicapped square-anti-prismatic [HoO(10)] polyhedron. Inter-molecular N-H?O hydrogen bonds occur. Intra-molecular O-H?O inter-actions link the complex mol-ecules and uncoordinated water mol-ecules.

(?-Acetato-?(2) O:O')[?-2,6-bis-({bis-[(pyri-din-2-yl-?N)meth-yl]amino-?N}meth-yl)-4-methyl-phenolato-?(2) O:O](metha-nol-?O)dizinc bis-(perchlorate).

Project description:The binuclear title complex, [Zn2(C33H33N6O)(CH3COO2)(CH3OH)](ClO4)2, was synthesized by the reaction between 2,6-bis-({[bis-(pyridin-2-yl)meth-yl]amino}-meth-yl)-4-methyl-phenol (H-BPMP), Zn(OAc)2 and NaClO4. The two Zn(II) ions are bridged by the phenolate O atom of the octadentate ligand and the acetate group. An additional methanol ligand is terminally coordinated to one of the Zn(II) ions, rendering the whole structure unsymmetric. Other symmetric dizinc complexes of BPMP have been reported. However, to the best of our knowledge, the present structure, in which the two Zn(II) ions are distinguishable by the number of coordinating ligands and the coordination geometries (octahedral and square-pyramidal), is unique. The dizinc complex is a dication, and two perchlorate anions balance the charge. The -OH group of the coordinating methanol solvent mol-ecule forms a hydrogen bond with a perchlorate counter-anion. One of the anions is disordered over two sets of sites with an occupancy ratio of 0.734?(2):0.266?(2).
