Bis{2-meth-oxy-6-[3-(methyl-amino)propyl-imino-meth-yl]phenolato}nickel(II) bis-(perchlorate).

ABSTRACT: The asymmetric unit of the title compound, [Ni(C(12)H(18)N(2)O(2))(2)](ClO(4))(2), consists of one-half of a centrosymmetric mononuclear Schiff base nickel(II) complex cation and one perchlorate anion. The Ni(II) ion, lying on the inversion center, is coordinated by two N atoms and two O atoms from two Schiff base ligands, forming a square-planar geometry. The crystal packing is stabilized by N-H?O hydrogen bonds.

Bis{?-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}bis-({2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}copper(II)).

Project description:The title compound, [Cu2(C9H10NO2)4], is built of discrete centrosymmetric dimers. The Cu(II) atoms are each five coordinated by two deprotonated Schiff base ligands that are bonded differently to the metal atoms. Of the two phenolate O atoms, one is coordinated to one Cu(II) atom, whereas another bridges the two metal atoms. The basal plane of the square pyramid around Cu(II) atoms is formed by the imino N and phenolate O atoms of the bidentate and the monodentate/bidentate Schiff base ligands. The bridging phenolate oxygen occupies the apical position of the coordination sphere with a considerably longer Cu-O bond length. In the crystal, the dimeric mol-ecules pack relative to each other in such a way that the Cu2O2 planes of adjacent dimers are orthogonal.

Bis{2-[3-(dimethyl-ammonio)-propyl-imino-methyl-?N]-6-meth-oxy-phenolato-?O}bis-(thio-cyanato-?N)nickel(II).

Project description:The asymmetric unit of the title complex, [Ni(NCS)(2)(C(13)H(20)N(2)O(2))(2)], consists of two half-mol-ecules, both of which are completed by crystallographic inversion symmetry (Ni(2+) site symmetry = in both cases). Both metal ions are six-coordinated in distorted trans-NiO(2)N(4) geometries arising from two N,O-bidentate Schiff base ligands and two N-bonded thio-cyanate ions. The mol-ecular conformations are reinforced by two intra-molecular N-H?O hydrogen bonds.

Di-?-thio-cyanato-?N:N-bis-({5-meth-oxy-2-[3-(methyl-amino)propyl-imino-meth-yl]phenolato-?O,N,N'}copper(II)).

Project description:The title thio-cyanate-bridged dinuclear copper(II) complex, [Cu(2)(C(12)H(17)N(2)O(2))(2)(NCS)(2)], possesses crystallographic inversion symmetry. Each Cu(II) atom is five-coordinated by one imine N, one amine N and one phenolate O atom of the Schiff base ligand, and by two N atoms from two bridging thio-cyanate ligands, forming a square-pyramidal geometry. Beside the two thio-cyanate bridges, there are two intra-molecular N-H?O hydrogen bonds, which further link the two Cu(C(12)H(17)N(2)O(2))(NCS) units. The Cu?Cu separation is 3.261?(2)?Å. Parts of the methylaminopropylimino segment are disordered over two sites with occupancies of 0.669(9) and 0.331(9).

Crystal structure of bis-{μ-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}bis-({2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}nickel(II)) involving different coordination modes of the same Schiff base ligand.

Project description:The structure of the title compound, [Ni2(C9H10NO2)4], is built up by discrete centrosymmetric dimers. Two nitro-gen and three oxygen atoms of two Schiff base ligands singly deprotonated at the phenolate site form a square-pyramidal environment for each metal atom. The ligands are bonded differently to the metal centre: one of the phenolic O atoms is bound to one nickel atom, whereas another bridges the two metal atoms to form the dimer. The Ni-N/O distances fall in the range 1.8965 (13)-1.9926 (15) Å, with the Ni-N bonds being slightly longer; the fifth contact of the metal to the bridging phenolate oxygen atom is substanti-ally elongated [2.533 (1) Å]. A similar coordination geometry was observed in the isomorphous Cu analogue previously reported by us [Sydoruk et al. (2013 ▸). Acta Cryst. E69, m551-m552]. In the crystal, the [Ni2 L 4] mol-ecules form sheets parallel to the ab plane with the polar meth-oxy groups protruding into the inter-sheet space and keeping the sheets apart. Within a sheet, the mol-ecules are stacked relative to each other in such a way that the Ni2O2 planes of neighbouring mol-ecules are orthogonal.

Bis{2-[3-(dimethyl-amino)propyl-imino-meth-yl]-6-methoxy-phenolato-κN,N',O}nickel(II).

Project description:The centrosymmetric title complex, [Ni(C(13)H(19)N(2)O(2))(2)], is a mononuclear nickel(II) complex. The Ni(II) atom is coordinated by four N atoms and two O atoms of two deprotonated Schiff base ligands, forming a slightly distorted octa-hedral coordination configuration, in which the tertiary N atoms occupy the axial positions.

Bis{2-[3-(dimethyl-amino)-propyl-imino-meth-yl]-6-meth-oxy-phenolato}-?N,N',O;?N,O-zinc(II) dihydrate.

Project description:In the title mononuclear Zn(II) complex, [Zn(C(13)H(19)N(2)O(2))(2)]·2H(2)O, the Zn(II) atom is coordinated by two O atoms and three N atoms from two crystallographically different Schiff base ligands in a distorted trigonal-bipyramidal environment. One O and two N atoms constitute the base of the pyramid, and one O and one N atoms occupy the apical positions. Inter-molecular O-H?O and O-H?N hydrogen bonds between the lattice water mol-ecules and N/O atoms of the Schiff base ligands stabilize the conformation, whereas inter-molecular O-H?O hydrogen bonds between the two lattice water mol-ecules lead to a chain structure in [001].

[2-Formyl-4-methyl-6-({2-[2-(4-nitro-benzyl-amino)-ethyl-amino]-ethyl-imino}-meth-yl)phenolato]nickel(II) perchlorate.

Project description:In the unsymmetrical title complex, [Ni(C(20)H(23)N(4)O(4))]ClO(4), the coordination geometry for the Ni(II) atom can be described as square planar. The aromatic rings in the two ligands are almost vertical, with a dihedral angle of 85.3°. In the crystal, cations and anions are linked by weak C(N)-H?O hydrogen bonding.

Crystal structure of di-chlorido-bis-{μ-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}{2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}cadmium(II)cobalt(III) monohydrate.

Project description:The title compound, [CoCd(C9H10NO2)3Cl2]·H2O, is a solvatomorph of the corresponding hemihydrate recently published by us [Nesterova et al. (2018 ▸). Appl. Cat. A, 560, 171-184]. The current structure reveals different cell parameters and space group compared with the published one while both are monoclinic with almost the same cell volume. The title compound is formed of discrete neutral dinuclear mol-ecules with no crystallographically imposed symmetry and water mol-ecules of crystallization. The overall geometry about the cobalt(III) ion is octa-hedral with an N3O3 environment; each ligand acts as a meridional ONO donor. The CdII coordination sphere approximates an irregular square pyramid with a chlorine atom at the apex. There is significant shortening of a Cd-O bond length to the oxygen atom of the methoxo group on one of the ligands [2.459 (3) Å] compared to the corresponding distance in the published structure [2.724 (7) Å], while other Cd-Cl/N/O bonds remain roughly the same. In the crystal lattice, the heterometallic mol-ecules, which are related by the crystallographic n-glide plane and inter-linked by weak hydrogen bonds to solvent water mol-ecules, form columns along [101]. Adjacent columns lie anti-parallel to each other.

Project description:In the title complex, [Cu(C(12)H(15)Cl(2)N(2)O)(2)], the Cu(II) ion is coordinated by one N,O-bidentate and one N,N',O-tridentate Schiff base ligand, resulting in a distorted CuN(3)O(2) square-based pyramidal coordination for the metal ion, with the O atoms lying trans to each other in the basal plane.

Diazido-bis{2-[3-(dimethyl-amino)propyl-imino-meth-yl]phenol}manganese(III) perchlorate.

Project description:The title compound, [Mn(N(3))(2)(C(12)H(18)N(2)O)(2)]ClO(4), was synthesized from manganese(III) acetate, sodium azide and 2-[3-(dimethyl-amino)propyl-imino-meth-yl]phenol by a hydro-thermal reaction. The Mn(III) ion is hexa-coordinated by two N and two O atoms from two phenolate ligands and two N atoms from two azide ligands. The Mn(III) cation lies on an inversion centre and, as a result, the asymmetric unit comprises one half-mol-ecule.
