چکیده
In the title compound, [Zn(2)(C(36)H(42)N(4)O(2))(CH(3)COO)(2)]·2CH(3)CH(2)OH, a centrosymmetric dinuclear zinc macrocyclic complex is accompanied by two half-occupied ethanol solvent molecues resulting in a 1:2 macrocycle-solvent composition. The Zn(II) atom has a square-pyramidal geometry arising from an N(2)O(3) donor set, being coordinated by two N atoms and two O atoms from the macrocyclic ligand in the equatorial sites and one O atom from an acetate anion in the apical site. The two Zn(II) atoms are linked by two phenolate O atoms, generating a four-membered Zn(2)O(2) ring at the centre of the macrocycle. The tert-butyl group shows rotational disorder over two sets of sites in a 0.552 (12):0.448 (12) ratio. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds are seen and a short intra-molecular C-H⋯O contact occurs.

In the title centrosymmetric dinuclear nickel complex, [Ni(2)(C(22)H(30)N(4)O(2))(NO(3))(2)], each of the two Ni(II) atoms has a distorted octa-hedral geometry, defined by two N atoms and two O atoms from the macrocyclic ligand and two O atoms from a chelating nitrate anion. The two Ni atoms are bridged by two phenolate O atoms, forming a four-membered Ni(2)O(2) ring.

In the centrosymmetric and dinuclear title complex, [Mn(2)(C(22)H(22)N(4)O(2))(ClO(4))(2)], the two Mn atoms are bridged by two phenolate O atoms of the N(4)O(2) macrocycle with an Mn⋯Mn distance of 2.9228 (11) Å. The distorted square-pyramidal N(2)O(3) coordination geometry is completed by an O atom derived from a perchlorate anion.

The dinuclear title complex, [Cu(2)(C(46)H(38)N(4)O(2))Cl(2)]·0.5C(2)H(5)OH·2H(2)O, is located on crystallographic inversion centres with two half-mol-ecules in the asymmetric unit. The two Cu(II) atoms are coordinated by a hexa-dentate dianionic ligand formed in situ from the condensation of two tridentate ligands by four imine N atoms and two bridging phenolate O atoms along with two Cl atoms...

The title compound, [Cu(2)(C(31)H(30)Cl(2)N(4)O(4))Cl(2)]·CH(3)CN, was synthesized by cyclo-condensation between N,N'-bis-(2-fur-yl)-N,N'-bis-(3-formyl-5-chloro-salicylaldehyde)ethyl-enediamine and 1,3-diamino-propane in the presence of Cu(II) ions. It is an unsymmetrical dinuclear Cu(II) complex. The coordination geometry for each Cu(II) atom can be discribed as distorted square-pyramidal. The...

The title compound, C(46)H(40)N(4)O(2)·0.33C(6)H(12), was obtained unintentionally as a product of an attempted synthesis of a cadmium(II) complex of the [2,6-{PhSe(CH(2))(2)N=CPh}(2)C(6)H(2)(4-Me)(OH)] ligand. The full tetra-imino-diphenol macrocyclic ligand is generated by the application of an inversion centre. The macrocyclic ligand features strong intra-molecular O-H⋯N hydrogen bonds. The ...
