چکیده
In the title compound, [Zn(C(7)H(4)FO(2))(2)(C(5)H(6)N(2))(2)] or [Zn(fa)(2)(2-pa)(2)] (Hfa is 2-fluoro-benzoic acid and 2-pa = pyridin-2-amine), the asymmetric unit contains one Zn(II) cation, two fa ligands and two 2-pa ligands, wherein the Zn(II) displays a distorted tetra-hedral geometry, being surrounded by two monodentate fa ligands with Zn-O distances of 1.962 (2) and 1.976 (3) Å, and by two 2-pa ligands with distances involving pyridyl N atoms of 2.069 (2) and 2.056 (2) Å. The F atoms of the fa ligands are equally disordered over two sites, viz. the 2- and 6-positions of fa. The mononuclear complex mol-ecules are joined by N-H⋯O and N-H⋯F hydrogen bonds into a two-dimensional layer, which is further constructed into a three-dimensional supra-molecular network by weak C-H⋯F inter-actions and effective π-π stacking [centroid-centroid separation of 3.74 (3) Å] between the inter-layer aromatic rings and adjacent heterocycles.

In the title compound, [Ni(NO(3))(2)(C(24)H(20)N(2))(2)], the Ni(II) atom has a distorted pseudo-octa-hedral coordination geometry defined by two chelating nitrate groups and two pyridine N atoms of the monodentate N-(triphenyl-meth-yl)pyridin-2-amine ligands. Intra-molecular N-H⋯O hydrogen bonds help to establish the configuration.

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, [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.
