Bis(2-dimethylamino-1,10-phenanthroline-κ2N,N′)bis­(thio­cyanato-κN)nickel(II) methanol disolvate

In the title complex, [Ni(NCS)2(C14H13N3)2]·2CH3OH, the NiII atom lies on a crystallographic twofold rotation axis and is in a slightly distorted octahedral NiN6 coordination environment. The crystal structure is stabilized by a combination of weak π–π stacking interactions between symmetry-related 1,10-phenanthroline ligands [centroi–centroid distance between benzene rings = 3.5936 (18) Å] and weak O—H⋯S, C—H⋯O and C—H⋯S hydrogen bonds between methanol and complex molecules.

Aqua­bis(3′-hydr­oxy-2,2′-bipyridine-3-olato-κ2N,N′)zinc(II)

In the title complex, [Zn(C10H7N2O2)2(H2O)], the ZnII ion and water O atom are located on a crystallographic twofold rotation axis and the metal atom assumes a distorted trigonal-bipyramidal ZnN4O coordination geometry. An intramolecular O—H⋯O hydrogen bond occurs within the ligand and intermolecular O—H⋯O hydrogen bonds involving the water molecule result in a sheet structure in the crystal structure. In addition, a short C—O⋯π contact between the O atom of the deprotonated hydroxyl group and a nearby pyridine ring [O⋯Cg = 3.977 (2) Å, where Cg is the centroid of the pyridine ring] is observed.

(2-Meth-oxy-1,10-phenanthroline-κN,N')bis-(thio-cyanato-κN)zinc(II).

In the title complex, [Zn(NCS)2(C13H10N2O)], the ZnII ion is in a distorted tetrahdral ZnN2Cl2 coordination environment. In the crystal structure, there is a weak π–π stacking interaction between adjacent 1,10-phenanthroline rings, with a pyridine centroid–centroid distance of 3.6620 (15) Å.

(Dicyanamido)[tris­(2-pyridylmeth­yl)amine]zinc(II) perchlorate

In the title complex, [Zn(C2N3)(C18H18N4)]ClO4, the ZnII ion has a slightly distorted trigonal–bipyramidal ZnN5 coordination geometry. The crystal structure is stabilized by weak intermolecular C—H⋯O and C—H⋯N hydrogen bonds. In addition, there are relatively close contacts between the O atoms of the perchlorate anion and symmetry-related pyridine rings [O⋯Cg = 3.179 (3) and 3.236 (3) Å, where Cg is the centroid of a pyridine ring], and between the terminal N atom of the dicyanamide ligand and pyridine rings [N⋯Cg = 3.381 (4)–3.761 (3) Å]. The central N atom of the dicyanamide ligand is disordered over two sites in an approximately 0.6:0.4 ratio.

catena-Poly[[(1,10-phenanthroline-κ2N,N′)copper(I)]-μ-thio­cyanato-κ2N:S]

In the title complex, [Cu(NCS)(C12H8N2)]n, the CuI ion is in a distorted tetrahedral CuN3S coordination geometry. The thiocyanate ligand acts as bridging ligand, forming chains along [100]. A crystallographic mirror plane runs through the CuI ion, the thiocyanate ligand and the middle of the phenanthroline ligand.

Diaqua-(nitrato-κO,O')[2-(1H-1,2,4-triazol-1-yl-κN)-1,10-phenanthroline-κN,N']cadmium(II) nitrate.

In the title complex, [Cd(C14H9N5)(NO3)(H2O)2]NO3, the CdII ion is coordinated in a distorted pentagonal-bipyramidal geometry. The equatorial sites are occupied by a 2-(1H-1,2,4-triazol-1-yl)-1,10-phenanthroline ligand in a tridentate coordination mode and a bis-chelating nitrate ligand. Two aqua ligands are coordinated at the axial sites. All non-H atoms in the equatorial plane are co-planar within 0.0673 Å. In the crystal, intermolecular O—H⋯O and O—H⋯N hydrogen bonds connect the components into a two-dimensional network parallel to (001). In addition, there is a π–π stacking interaction between symmetry-related benzene rings, with a centroid–centroid distance of 3.598 (3) Å.

Chlorido[2,2′-(oxydimethyl­ene)­dipyridine]copper(II) perchlorate–aqua­chlorido[2,2′-(oxydimethyl­ene)­dipyridine]copper(II) perchlorate (1/1)

The asymmetric unit of the title compound, [CuCl(C12H12N2O)][CuCl(C12H12N2O)(H2O)](ClO4)2, contains two different discrete cations. In one cation, the CuII ion is coordinated in a slightly distorted square-planar geometry, while in the other the CuII ion is in a slightly distorted square-pyramidal environment. In the crystal structure, there are O—H⋯O hydrogen bonds between coordinated water molecules and perchlorate anions. Both types of cations are linked into one-dimensional chains along the b axis by weak electrostatic Cu⋯Cl interactions, with Cu⋯Cl distances of 2.8088 (16) and 3.2074 (17) Å.
