چکیده
In the title salt, [Zn(C(22)H(24)N(4)O)(CH(3)CN)][Zn(ClO(4))(C(22)H(24)N(4)O)(CH(3)CN)](ClO(4))(3), two differently coordinated zinc cations occur. In the first complex, the metal ion is coordinated by the N,N',N'',O-tetra-dentate acetamide ligand and an acetonitrile N atom, generating an approximate trigonal-bipyramidal coordination geometry, with the O atom in an equatorial site and the acetonitrile N atom in an axial site. In the second complex ion, a perchlorate ion is also bonded to the zinc ion, generating a distorted trans-ZnO(2)N(4) octa-hedron. Of the uncoordinating perchlorate ions, one lies on a crystallographic twofold axis and one lies close to a twofold axis and has a site occupancy of 0.5. N-H⋯O and N-H⋯(O,O) hydrogen bonds are observed in the crystal. Disordered solvent mol-ecules occupy about 11% of the unit-cell volume; their contribution to the scattering was removed with the SQUEEZE routine of the PLATON program [Spek (2009 ▶). Acta Cryst. D65, 148-155.].

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,...

In the title compound, [Cu(ClO(4))(C(2)H(3)N)(C(15)H(19)N(3)O)]ClO(4), the Cu(II) ion is coordinated by three N atoms and a hydroxyl-O atom of the tetra-dentate ligand, an O atom of a perchlorate ion and an N atom of an acetonitrile ligand giving a tetra-gonally distorted octa-hedral environment around the copper(II) atom.

In the title compound, [Co(NCS)(2)(C(19)H(17)N(5)O(2))(2)(CH(3)OH)(2)], the Co(II) atom lies on an inversion center and is coordinated by two isothio-cyanate N atoms, two O atoms of methanol mol-ecules and two pyridine N atoms in a slightly distorted octa-hedral environment. Inter-molecular O-H⋯O and N-H⋯N hydrogen bonds join the complex mol-ecules into layers parallel to the bc plane.

The title compound, [Zn(2)(C(42)H(38)N(9)O(3))(2)(NO(3))(2)]·2CH(3)CN·0.5H(2)O, is a bis-phenolate-bridged dinuclear Zn(II) complex. The asymmetric unit comprises half the zinc complex (the full complex is completed by the application of a centre of inversion), one acetonitrile solvent mol-ecule and a quarter of a water mol-ecule (located on a twofold axis with half-occupancy; H atoms were not ...

The title compound, [Fe(C12H8N4S)2(CH3OH)2](ClO4)2, crystallized in the solvent-free form from a methanol solution. The Fe(II) ion is located on a centre of inversion. The distorted N4O2 octa-hedral coordination geometry is formed by two N,N'-chelating equatorial 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands and axially coordinating methanol coligands, resulting in the mononuclear trans-(N ...
