ABSTRACT: In the crystal structure of the title compound, (C12H9N2)2[ZnCl4]·H2O, the two independent 1,10-phenanthrolinium cations are bridged by the water mol-ecule and the tetrahedral tetrachloridozincate anion via N-H?O, O-H?Cl and N-H?Cl hydrogen bonds, forming chains along . The chains are linked via C-H?Cl hydrogen bonds and a number of ?-? inter-actions [centroid-centroid distances vary from 3.5594?(14) to 3.7057?(13)?Å], forming a three-dimensional network. In each 1,10-phenanthrolinium cation, there is a short N-H?N inter-action.
Project description:In the structure of the 1:1 proton-transfer compound of 1,10-phenanthroline with 4,5-dichloro-phthalic acid, C(12)H(9)N(2) (+)·C(8)H(3)Cl(2)O(4) (-), determined at 130?K, the 1,10-phenanthrolinium cation and the hydrogen 4,5-dichloro-phthalate anion associate through a single N-H?O(carbox-yl) hydrogen bond giving discrete units which have no extension except through a number of weak cation C-H?O(anion) associations and weak cation-anion aromatic ring ?-? inter-actions [minimum centroid-centroid separation = 3.6815?(12)?Å]. The anions are essentially planar "[maximum deviation 0.214?(1)?Å (a carboxyl O)] with the syn-related H atom of the carboxyl group, forming a short intra-molecular O-H?O(carbox-yl) hydrogen bond.
Project description:In the crystal structure of the title salt, (C10H10N2)[ZnCl4], the bi-pyridine-diium dication is not planar, with a dihedral angle of 37.21?(9)° between the planes of the two pyridine rings. In the crystal, the slightly distorted [ZnCl4](2-) anions are packed into rods parallel to , with the organic cations arranged in corrugated layers parallel to (100). Cations and anions are linked through N-H?Cl hydrogen bonds, forming chains parallel to [20-1]. Additional C-H?Cl inter-actions consolidate the crystal packing.
Project description:In the crystal of the title compound, C(16)H(17)N(2) (+)·NO(3) (-)·H(2)O, the tetra-methyl-1,10-phenanthrolinium cations, nitrate anions and lattice water mol-ecules are all located on a mirror plane with the methyl H atoms of the cation equally disordered over two sites about the mirror plane. The cation, anion and water mol-ecule are linked by O-H?O and N-H?O hydrogen bonds into a sheet parallel to the bc plane. ?-? stacking between phenanthroline ring systems is observed in the crystal structure, the centroid-centroid distance being 3.4745?(6)?Å.
Project description:The title hydrated molecular salt, 2C(12)H(9)N(2) (+)·C(14)H(6)O(8)S(2) (2-)·6H(2)O, consists of 1,10-phenanthrolinium (phen-H(+)) cations, anthraquinone-1,5-disulfonate (AQDS(2-)) anions, which occupy a centre of inversion, and water molecules of crystal-lization. In the crystal, a supra-molecular network structure is formed via N-H?O and O-H?O hydrogen bonds and weak C-H?O and ?-? stacking inter-actions [centroid-centroid distances = 3.651?(6) and 3.545?(8)?Å].
Project description:In the preparation of the title hydrated salt, C14H13N2 (+)·C10H5O8 (-)·H2O, a proton has been transfered to the 2,9-dimethyl-1,10-phenanthrolinium cation, forming a 2,4,5-tri-carb-oxy-benzoate anion. In the anion, the mean planes of the protonated carboxyl-ate groups form dihedral angles of 11.0?(5), 4.4?(5) and 80.3?(4)° with the benzene ring to which they are attached. The mean plane of the deprotonated carboxyl-ate group forms a dihedral angle of 10.6?(5)° with the benzene ring. In the crystal, the anions are involved in carb-oxy-lic acid O-H?Ocarbox-yl hydrogen bonds, generating a two-dimensional network parallel to (001) containing R 4 (4)(28) and R 4 (4)(32) motifs. The 2,9-dimethyl-1,10-phenanthrolinium cations and water mol-ecules reside between the anion layers and are connected to the anions via N-H?Owater and Owater-H?Ocarbox-yl hydrogen bonds. An intra-molecular O-H?O hydrogen bond is also observed in the anion.
Project description:The title compound, C(20)H(14)N(4)OS·0.5CH(2)Cl(2)·H(2)O, contains 1,10-phenanthroline and benzoyl fragments that adopt cisoid and transoid conformations respectively, with respect to the S atom. In the crystal, mol-ecules are linked by inter-molecular O-H?O, O-H?N, N-H?O and C-H?O hydrogen bonds, forming chains along . Weak C-H?? and slipped ?-? stacking inter-actions [centroid-centroid distances = 3.715?(3), 3.684?(3) and 3.574?(2)?Å] are also observed. In addition to an ordered water mol-ecule of solvation, there is a disordered dichloro-methane solvent mol-ecule which was difficult to model correctly. The contributions to the electron density for this mol-ecule was removed using the SQUEEZE procedure in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].
Project description:The structure of the title compound, [CrCl(C12H8N2)2(H2O)][ZnCl4]·H2O, has been determined from synchrotron data. The Cr(III) ion is bonded to four N atoms from two 1,10-phenanthroline (phen) ligands, one water mol-ecule and a Cl atom in a cis arrangement, displaying an overall distorted octa-hedral coordination environment. The Cr-N(phen) bond lengths are in the range of 2.0495?(18) to 2.0831?(18)?Å, while the Cr-Cl and Cr-(OH2) bond lengths are 2.2734?(7) and 1.9986?(17)?Å, respectively. The tetra-hedral [ZnCl4](2-) anion is slightly distorted owing to its involvement in O-H?Cl hydrogen bonding with coordinating and non-coordinating water mol-ecules. The two types of water mol-ecules also inter-act through O-H?O hydrogen bonds. The observed hydrogen-bonding pattern leads to the formation of a three-dimensional network structure.
Project description:In the cation of the title mol-ecular salt, C(18)H(13)N(4)O(+)·Cl(-)·H(2)O, the dihedral angle between the mean planes of the 1,10-phenanthroline system and the phenol ring is 14.40?(19)°. The crystal packing is stabilized by O-H?O hydrogen bonds, weak N-H?Cl and O-H?Cl inter-molecular inter-actions and ?-? stacking inter-actions [centroid-centroid distance = 3.6944?(13) and 3.9702?(12)?Å].
Project description:The asymmetric unit of the title compound, (C6H18N2)[ZnCl4], consists of one tetra-chlorido-zincate anion and two half-N,N,N'N'-tetra-methyl-ethylenedi-ammonium cations. Each of the two di-ammonium cations is located about an inversion center and one of them is disordered over two sets of sites in a 0.780?(17):0.220?(17) ratio. The Zn(II) atom has a slightly distorted tetra-hedral coordination environment. The cations and anions are connected via N-H?Cl hydrogen bonds into chains extending along [0-11].
Project description:Both the cation and anion of the title compound, (C(26)H(21)N(2))[AuCl(4)], are disposed about a plane of mirror symmetry. The 2,9-dimethyl-4,7-diphenyl-1,10-phenanthrolinium ring is oriented at a dihedral angle of 44.2?(1)° with respect to the planar phenyl ring systems. The Au(III) atom has a square-planar environment defined by four Cl atoms. The crystal structure is stabilized by C-H?? and Au?? ring-metal (3.551?Å) inter-actions. In the crystal structure, the mol-ecules stack along the c axis via N-H?N hydrogen-bond inter-actions.
