Diaqua-dichloridobis[quinazolin-4(1H)-one-?N(3)]nickel(II).

ABSTRACT: In the title complex, [NiCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center and is six-coordinated by two N atoms of 1H-quinazolin-4-one ligands, two chloride ions and two water mol-ecules. The water mol-ecules are involved in intra- and inter-molecular O-H?O and O-H?Cl hydrogen bonding. Inter-molecular N-H?O and N-H?Cl hydrogen bonds are formed between ligands. In addition, weak ?-? inter-actions are observed between the benzene rings of the ligands [centroid-centroid distance = 3.580?(3)?Å]. The inter-molecular hydrogen bonds and ?-? inter-actions lead to the formation of a three-dimensional supra-molecular network.

Diaqua-dichloridobis[quinazolin-4(1H)-one-?N]copper(II).

Project description:In the title complex, [CuCl(2)(C(8)H(6)N(2)O)(2)(H(2)O)(2)], the Cu(II) ion is located on an inversion center and is octahedrally coordinated by two N atoms of the 1H-quinazolin-4-one ligand, two chloride ligands and two aqua ligands. The axial Cu-O distances are significantly longer [2.512?(2)?Å], than the Cu-N [2.022?(2)?Å] and Cu-Cl [2.3232?(4)?Å] distances as a result of Jahn-Teller distortion. Aqua ligands are involved in intra- and inter-molecular hydrogen bonding, and N-H?O inter-molecular hydrogen bonds are formed between the organic ligands. In addition, weak ?-? inter-actions are observed between the benzene rings of the ligand [centroid-centroid distance = 3.678?(1)?Å].

Diaqua-dichloridobis(pyridine-?N)manganese(II).

Project description:The molecular title compound, [MnCl(2)(C(5)H(5)N)(2)(H(2)O)(2)], lies about an inversion centre. The Mn(II) atom is in an all-trans octa-hedral environment defined by two water mol-ecules, two chloride anions and two pyridine ligands. An inter-molecular hydrogen-bonding inter-action between a water mol-ecule and a chloride anion bonded to an adjacent Mn(II) atom generates an eight-membered ring. The crystal packing exhibits two inter-molecular ?-? stacking inter-actions between the aromatic rings, with centroid-centroid distances of 3.485?(12) and 3.532?(12)?Å.

Dichloridobis(thio-urea-?S)nickel(II).

Project description:The title complex, [NiCl(2)(CH(4)N(2)S)(2)], has been synthesized from the previously reported (diamino-methyl-idene)sulfonium chloride-thio-urea (3/2) salt [Zouihri (2012b ?). Acta Cryst. E68, o257]. The Ni(II) ion is coordinated in a distorted tetra-hedral geometry by two mol-ecules of thio-urea [Ni-S = 2.3079?(7) and 2.3177?(6)?Å] and two chloride anions [Ni-Cl = 2.2516?(7) and 2.2726?(7)?Å]. The bond angles at the Ni atom lie between 96.69?(2) and 115.40?(3)°, while the dihedral angle between the mean planes of the two thio-urea ligands is 6.36?(15)°. The crystal structure is characterized by intra- and inter-molecular N-H?Cl hydrogen bonds, which lead to the formation of two-dimensional networks lying parallel to the ab plane. The networks are linked via classical N-H?Cl and N-H?S hydrogen bonds, forming a three-dimensional arrangement.

Project description:There are two independent mol-ecules in the the asymmetric unit of the title compound, C(11)H(14)N(2)O. The heterocyclic ring of the bicyclic system has a sofa conformation, with the C atom bearing the two methyl groups displaced by 0.541 (7) Å from the rest of the atoms of the ring [planar to within 0.064 (9) Å]. Mol-ecules are linked into centrosymmetric dimers via N-H⋯O hydrogen bonds.

Dichloridobis(3,4,5-trimethyl-1H-pyrazole-κN)cobalt(II).

Project description:In the title compound, [Co(II)Cl(2)(C(6)H(10)N(2))(2)], a pair of 3,4,5-trimethyl-pyrazoles act as monodentate ligands. Two Cl(-) anions are also bonded directly to the Co(II) atom, which has a CoN(2)Cl(2) chromophore in a slightly distorted tetra-hedral geometry. The two mol-ecules in the asymmetric unit are related by an approximate twofold rotation roughly parallel to the a axis. The amino H atom in the pyrazole ring participates in weak N-H⋯Cl hydrogen bonds to form chains that propagate roughly parallel to the c axis.

The crystal packing is governed by inter-molecular hydrogen-bonding inter-actions of the O-H?O, N-H?O and C-H?O types.

Diaqua-(2,2'-bipyridine-6,6'-dicarboxyl-ato)nickel(II).

Project description:In the title compound, [Ni(C(12)H(6)N(2)O(4))(H(2)O)(2)], the Ni(II) atom (site symmetry 2) displays a distorted cis-NiN(2)O(4) octa-hedral coordination geometry with two N atoms and two O atoms of the tetra-dentate 2,2'-bipyridine-6,6'-dicarboxyl-ate ligand in the equatorial plane and two water mol-ecules in axial positions. The complete dianionic ligand is generated by crystallographic twofold symmetry. In the crystal, a two-dimensional supra-molecular structure parallel to (001) is formed through O-H?O hydrogen-bond inter-actions between the coordinated water mol-ecules and the O atoms of nearby carboxyl-ate groups.
