Project description:In the crystal structure of the title complex, [Zn(2)Cl(4)(C(12)H(8)N(2))(2)], each of the two five-coordinated Zn(II) atoms displays a strongly distorted trigonal-bipyramidal geometry defined by two N atoms from the chelate ligand and by one terminal and two bridging chloride anions. The crystal structure is stabilized by C-H⋯Cl inter-actions. There is inter-molecular π-π stacking between adjacent phenanthroline ligands, with a centroid-centroid distance of 3.151 (3) Å.

Project description:In the crystal structure of the title compound, [ZnCl(2)(C(14)H(12)N(2)O(2))], the Zn(II) center is four-coordinated by two N atoms from one 2,9-dimeth-oxy-1,10-phenanthroline ligand and two Cl atoms. The coordination geometry is distorted tetra-hedral, as the Zn-N bond distances are shorter than the Zn-Cl distances, and the Cl-Zn-N and Cl-Zn-Cl bond angles are much larger than the N-Zn-N angle. For the ligand, the O and C atoms of the meth-oxy groups are almost in the plane defined by the phenanthroline ring. The two O atoms deviate from the phenanthroline mean plane by 0.076 (2) and 0.084 (2) Å, and the two methyl C atoms deviate from the phenanthroline mean plane by 0.035 (3) and 0.361 (3) Å. There are medium π-π stacking interactions between two parallel phenanthroline rings with a centroid-centroid distance of 3.7860 (2) Å and a dihedral angle between the plane defined by the two parallel phenanthroline rings of 1.13 (5)°.

Project description:The title compound, [Cd2Br4(C24H16N2)2], consists of a centrosymmetric dimeric unit in which two Br atoms bridge two Cd(II) atoms, forming a four-membered ring. A terminal Br atom and a bidentate chelating 4,7-diphenyl-1,10-phenanthroline ligand complete a square-pyramidal geometry for the Cd(II) atom. In the crystal, C-H⋯Br hydrogen bonds and π-π contacts between the pyridine and phenyl rings [centroid-centroid distances = 3.704 (4) and 3.715 (4) Å] lead to a three-dimensional supra-molecular structure.

Project description:A gold(III) salt of composition [AuCl2(C12H8N2)]PF6 was prepared and characterized by elemental and mass spectrometric analysis (ESI(+)-QTOF-MS), 1H nuclear magnetic resonance measurements and by single-crystal X-ray diffraction. The square-planar coordination sphere of AuIII comprises the bidentate 1,10-phenanthroline ligand and two chloride ions, with the AuIII ion only slightly shifted from the least-squares plane of the ligating atoms (r.m.s. = 0.018 Å). In contrast to two other previously reported AuIII-phenantroline structures that are stabilized by inter-actions involving the chlorido ligands, the packing of the title compound does not present these features. Instead, the hexa-fluorido-phosphate counter-ion gives rise to anion⋯π inter-actions that are a crucial factor for the crystal packing.

Project description:The asymmetric unit of the title compound, C24H16N2·0.5CH3OH, is comprised of two independent bathophenanthroline mol-ecules (systematic name: 4,7-diphenyl-1,10-phenanthroline) and one methanol mol-ecule. The bathophenanthroline mol-ecules are not planar as there is a considerable rotation of all terminal phenyl rings with respect to the central phenanthroline units [dihedral angles in the range 52.21 (12)-62.14 (10)°]. In addition, a non-negligible torsion is apparent in one of the phenanthroline units: the angle between the mean planes of the two pyridine rings is 14.84 (13)°. The methanol solvent mol-ecule is linked to both N atoms of a bathophenanthroline mol-ecule through a bifurcated O-H⋯(N,N) hydrogen bond.

Project description:The title complex, [CuCl(C12H8N2)2][Mn(C7H3NO4)Cl(C12H8N2)]·CH3OH, consists of discrete [CuCl(phen)2](+) cations (phen is 1,10-phenanthroline), [MnCl(pydc)(phen)](-) anions (H2pydc is 2,6-pyridine-2,6-di-carb-oxy-lic acid) and one methanol solvent mol-ecule of crystallization per asymmetric unit. It should be noted, that a solvent-masking procedure as implemented in OLEX2 [Dolomanov et al. (2009). J. Appl. Cryst. 42, 339-341 ▶] was used to remove the electronic contribution from one disordered solvent molecule, presumably methanol. Only the atoms used in the refined model are reported in chemical formula and related values. The Cu(II) ion is five-coordinated by two phenanthroline ligands and one chloride ion in a distorted trigonal-bipyramidal geometry. The dihedral angle between the phen ligands is 65.21 (5)°. The Mn(II) ion is six-coordinated by one Cl atom, two N atoms from a phen ligand, as well one N atom and two O atoms from pydc in a distorted octa-hedral coordination geometry, with cis angles ranging from 72.00 (8) to 122.07 (8)° and trans angles ranging from 143.98 (8) to 163.15 (6)°. In the crystal, C-H⋯O, O-H⋯O and C-H⋯Cl hydrogen bonds, cation-anion π-π inter-actions between the phen ring systems with centroid-centroid distances in the range 3.881 (34)-4.123 (36) Å, as well as cation-cation, anion-anion π-π inter-actions between the phen rings with centroid-centroid distances in the range 3.763 (4)-3.99 (5) Å and pydc rings with centroid-centroid distances 3.52 (5) Å link the various components.

Project description:In the centrosymmetric title compound, [Ho(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Ho(III) atom is nine-coordinated by seven O atoms from the 3,4-dimeth-oxy-phenyl-acetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) mol-ecule. The L ligands are coordinated to the Ho(III) ions in three modes: chelating, bridging and bridging-tridentate. Intra-molecular C-H⋯O inter-actions occur. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions and weak aromatic π-π inter-actions between phen mol-ecules and the aromatic rings of the L ligands [centroid-centroid distance = 3.821 (2) Å].

Project description:The asymmetric unit of the title compound, [PtCl(3.66)I(0.34)(C(12)H(8)N(2))]·0.5(Cl(0.13)I(1.87)), contains a neutral Pt(IV) complex and one half of a halogen molecule. The Pt(IV) ion is six-coordinated in a distorted octa-hedral environment by two N atoms of the 1,10-phenanthroline ligand and Cl or I atoms. The refinement of the structure and the EDX analysis indicate that the compound is a solid solution in which there is some substitution of Cl for I and vice versa. The chemical formula of the pure state of the compound would have been [PtCl(4)(C(12)H(8)N(2))]·0.5I(2). In the analysed crystal, two Cl atoms are partially (ca 25% and 9%) replaced by I atoms, and the I(2) mol-ecule has a minor component modelled as ICl. As a result of the disorder, the different trans effects of the N and Cl/I atoms are not distinct. The complex displays inter-molecular π-π inter-actions between the six-membered rings, with a centroid-centroid distance of 3.771 (4) Å. There are also weak intra-molecular C-H⋯Cl hydrogen bonds.

Project description:In the title complex, [La(C₇H₄BrO₃)Cl₂(C₁₂H₈N₂)](n), the La(III) ion is eight-coordinated by two carboxyl-ate O atoms from two 5-bromo-salicylate ligands, two N atoms from a chelating 1,10-phenanthroline ligand and four bridging Cl atoms in a distorted square-anti-prismatic geometry. The La(III) ions are linked by bridging carboxyl-ate groups and chloride anions into a chain along [100]. An intra-molecular O-H⋯O hydrogen bond is formed in the 5-bromo-salicylate ligand. π-π inter-actions between the pyridine and benzene rings and between the benzene rings are observed [centroid-centroid distances = 3.794 (5) and 3.804 (4) Å].

Project description:In the crystal structure of the title monohydrate salt, [ZnCl(C(12)H(8)N(2))(2)][BiCl(4)(C(12)H(8)N(2))]·H(2)O, the ionic components are linked into three-dimensional supra-molecular channels by five pairs of C-H⋯Cl hydrogen bonds and π-π stacking inter-actions with an inter-planar distance of 3.643 (2) Å. The solvent water mol-ecules are lodged in the channels.
