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

ABSTRACT: 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).

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-μ-thio-cyanato-bis-({2,4-dichloro-6-[2-(diethyl-amino)ethyl-imino-meth-yl]phenolato}copper(II)).

Project description:The title compound, [Cu(2)(NCS)(2)(C(13)H(17)Cl(2)N(2)O)(2)], was obtained by the reaction of 3,5-dichloro-salicylaldehyde, N,N-diethyl-ethane-1,2-diamine, sodium thio-cyanate, and copper(II) acetate in an ethanol solution. It crystallizes as a centrosymmetric dimer with a very long Cu⋯S axial bond [2.972 (3) Å]. The Cu atom is five-coordinated by the three donor atoms of the Schiff base ligand, 2,4-dichloro-6-[(2-diethyl-amino-ethyl-imino)meth-yl]phenol, one N atom of a thio-cyanate group, and one S atom of a symmetry-related thio-cyanate group, forming a slightly distorted square-pyramidal geometry.

?-(2,6-Bis{[3-(di-methyl-amino)-prop-yl]imino-meth-yl}-4-methyl-phenolato)-?-hydroxido-bis-[(thio-cyanato-?N)copper(II)].

Project description:In the title compound, [Cu2(C19H31N4O)(OH)(NCS)2], the mol-ecular structure of the dinuclear complex reveals two penta-coordinated Cu(II) ions, which are bridged by the phenolate O atom of the ligand and by an exogenous hydroxide ion. The bridging atoms occupy equatorial positions in the coordination sphere of the metal atoms and complete the equatorial coordination planes with two ligand N atoms, the apical positions being occupied by thio-cyanate N atoms. The crystal structure also features ?-? stacking inter-actions involving the benzene rings with a centroid-centroid distance of 3.764?(4)Å. The crystal studied was a non-merohedral twin, with a refined BASF value of 0.203?(2).

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-meth-oxy-6-{[2-(methyl-ammonio)eth-yl]imino-meth-yl}phenolato)thio-cyanato-zinc(II) thio-cyanate hemihydrate.

Project description:The title mononuclear zinc(II) complex, [Zn(C(11)H(16)N(2)O(2))(2)(NCS)]NCS·0.5H(2)O, consists of a complex cation, a thio-cyanate anion, and half of a water mol-ecule. The Zn(II) atom in the cation is five-coordinated by two imine N and two phenolate O atoms from two bidentate Schiff base ligands, and by one N atom of a thio-cyanate ligand, forming a distorted trigonal-bipyramidal geometry. The ammonio H atoms are involved in hydrogen bonding with the ligand O atoms and the solvent water molecules (site occupation factor 0.5), which partially determines the conformation of the ligands.

Project description:In the title compound, [Cu(C(14)H(13)N(2)O(2))(NCS)(C(3)H(7)NO)], the Cu(2+) ion is coordinated by an N,N',O-tridentate 2-meth-oxy-6-(2-pyridylmethyl-imino-meth-yl)phenolate ligand, an N-bonded thio-cyanate ion and an O-bonded dimethyl-formamide (DMF) mol-ecule, resulting in a distorted CuN(3)O(2) square-based pyramidal geometry for the metal ion, with the DMF O atom in the apical site. The dihedral angle between the aromatic rings in the ligand is 8.70?(16)°. The S atom is disordered over two positions in a 0.901?(6):0.099?(6) ratio. In the crystal, mol-ecules inter-act by way of ?-? stacking inter-actions [centroid-centroid separation = 3.720?(2)?Å].
