Bis{2-amino-2-oxo-N-[(1E)-1-(pyridin-2-yl-?N)ethyl-idene]acetohydrazidato-?(2)N',O(1)}nickel(II).

ABSTRACT: In the title compound, [Ni(C(9)H(9)N(4)O(2))(2)], the Ni(II) ion is situated on a twofold rotation axis and is coordinated by two O and four N atoms from two tridentate {2-amino-2-oxo-N-[(1E)-1-(pyridin-2-yl-?N)ethyl-idene]acetohydrazidate ligands in a distorted octa-hedral geometry. In the crystal, N-H?O and N-H?N hydrogen bonds link the mol-ecules into columns in [001]. The porous crystal packing is further stabilized via ?-? inter-actions between the pyridine rings of neighbouring mol-ecules [centroid-centroid distance = 3.746?(3)?Å] with voids of 270?Å(3).

Crystal structures and Hirshfeld surface analysis of trans-bis-(thio-cyanato-κN)bis-{2,4,6-trimethyl-N-[(pyridin-2-yl)methyl-idene]aniline-κ2 N,N'}manganese(II) and trans-bis-(thio-cyanato-κN)bis-{2,4,6-trimethyl-N-[(pyridin-2-yl)methyl-idene]aniline-κ 2 N,N'}nickel(II)).

Project description:Two new mononuclear metal complexes involving the bidentate Schiff base ligand 2,4,6-trimethyl-N-[(pyridin-2-yl)methyl-idene]aniline (C15H16N2 or PM-TMA), [Mn(NCS)2(PM-TMA)2] (I) and [Ni(NCS)2(PM-TMA)2] (II), were synthesized and their structures determined by single-crystal X-ray diffraction. Although the title compounds crystallize in different crystal systems [triclinic for (I) and monoclinic for (II)], both asymmetric units consist of one-half of the complex mol-ecule, i.e. one metal(II) cation, one PM-TMA ligand, and one N-bound thio-cyanate anion. In both complexes, the metal(II) cation is located on a centre of inversion and adopts a distorted octa-hedral coordination environment defined by four N atoms from two symmetry-related PM-TMA ligands in the equatorial plane and two N atoms from two symmetry-related NCS- anions in a trans axial arrangement. The tri-methyl-benzene and pyridine rings of the PM-TMA ligand are oriented at dihedral angles of 74.18 (7) and 77.70 (12)° for (I) and (II), respectively. The subtle change in size of the central metal cations leads to a different crystal packing arrangement for (I) and (II) that is dominated by weak C-H⋯S, C-H⋯π, and π-π inter-actions. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to qu-antify these inter-molecular contacts, and indicate that the most significant contacts in packing are H⋯H [48.1% for (I) and 54.9% for (II)], followed by H⋯C/C⋯H [24.1% for (I) and 15.7% for (II)], and H⋯S/S⋯H [21.1% for (I) and 21.1% for (II)].

{N,N'-Bis[1-(2-pyrid-yl)ethyl-idene]propane-1,2-diamine}-bis(thio-cyanato-κN)-nickel(II).

Project description:In the title complex, [Ni(NCS)(2)(C(17)H(20)N(4))], the Ni(2+) ion (site symmetry 2) is coordinated by the N,N,N,N-tetra-dentate Schiff base ligand and two thio-cyanate ligands, forming a distorted NiN(6) octa-hedral geometry, with the thio-cyanate N atoms in a trans orientation. The pendant methyl group of the central propane-1,2-diamine fragment of the ligand is statistically disordered over two sets of positions. In the crystal, weak aromatic π-π stacking between pyridine rings [centroid-centroid separation = 3.7081 (17) Å] may help to establish the packing.

Bis[2-(pyridin-2-yl)ethanol-κN,O]bis-(thio-cyanato-κN)nickel(II).

Project description:In the title complex, [Ni(NCS)(2)(C(7)H(9)NO)(2)], the Ni(II) atom is in a distorted octa-hedral coordination environment defined by two N atoms of the two thio-cyanate ions and by the N and O atoms of the two chelating 2-(pyridin-2-yl)ethanol ligands. The complex mol-ecule is located around a crystallographic inversion center. In the crystal, mol-ecules are connected into a two-dimensional polymeric structure parallel to (100) by O-H⋯S hydrogen bonds.
