ABSTRACT: In the mol-ecule of the title compound, [HgI(2)(C(24)H(16)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from the bidentate 4,7-diphenyl-1,10-phenanthroline and two iodide ligands. There is a ?-? contact between the pyridine and phenyl rings [centroid-to-centroid distance = 4.2387?(4)?Å].

4,7-Diphenyl-1,10-phenanthroline methanol hemisolvate.

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.

Dichlorido(2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline-?N,N')mercury(II) acetonitrile hemisolvate.

Project description:The asymmetric unit of the title compound, [HgCl(2)(C(26)H(20)N(2))]·0.5CH(3)CN, contains two crystallographic-ally independent [HgCl(2)(C(26)H(20)N(2))] mol-ecules and one acetonitrile solvent mol-ecule. The Hg(II) atoms are four-coordin-ated in distorted tetra-hedral configurations by two N atoms from 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline ligands and two Cl atoms. The ligand ring systems are not planar. The phenyl rings are oriented at dihedral angles of 74.61?(3) and 66.00?(3)° in the two molecules. In the crystal structure, ?-? contacts between phenanthroline rings [centroid-centroid distances = 3.809?(1), 3.686?(1), 3.986?(1), 3.877?(1), 3.697?(1), 3.789?(1), 3.745?(1), 3.797?(1) and 3.638?(1)?Å] may stabilize the structure.

4,7-Diphenyl-2,9-bis-(trichloro-meth-yl)-1,10-phenanthroline.

Project description:In the title compound, C(26)H(14)Cl(6)N(2), the phenanthroline ring system is essentially planar, with an r.m.s. deviation of 0.048?(6)?Å, and makes dihedral angles of 64.8?(14) and 66.6?(6)° with the two terminal phenyl rings. One of the trichloro-methyl groups is disordered over two positions, with occupancies of 0.42?(2) and 0.58?(2).

trans-Bis(4,7-diphenyl-1,10-phenanthroline-?N,N')bis-(nitrato-?O,O')zinc(II).

Project description:The title compound, [Zn(NO(3))(2)(C(24)H(16)N(2))(2)], is a twofold axially symmetric coordination compound. Given that the Zn-O interactions [2.4926?(15) and 2.6673?(15)?Å] can be considered as weakly bonding and the nitrate ions share the same C(2) axis of the Zn(dpp)(2) fragment (dpp is 4,7-diphenyl-1,10-phenanthroline), these anions belong to the coordination sphere of Zn(2+), leading to a complex with an overall coordination number of 8 for the metal ion.

Dichlorido(4,7-diphenyl-1,10-phenanthroline-?N,N')gold(III) tetra-chloridoaurate(III).

Project description:In the cation of the title compound, [AuCl(2)(C(24)H(16)N(2))][AuCl(4)], the Au(III) atom is four-coordinated in a distorted square-planar configuration by two N atoms from a 4,7-diphenyl-1,10-phenanthroline ligand and two terminal Cl atoms. In the anion, the Au(III) atom has a square-planar coordination. In the crystal structure, intra- and inter-molecular C-H?Cl hydrogen bonds are found.

Di-?-bromido-bis-[bromido(4,7-diphenyl-1,10-phenanthroline-?(2) N,N')cadmium].

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 ?-? 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.

(4,7-Diphenyl-1,10-phenanthroline-?N,N')dimethyl-bis-(thio-cyanato-?N)tin(IV).

Project description:In the title compound, [Sn(CH(3))(2)(NSC)(2)(C(24)H(16)N(2))], a 1:1 adduct of dimethyl-tin diisothio-cyanate with 4,7-diphenyl-1,10-phenanthroline, the Sn(IV) atom shows a slightly distorted octa-hedral SnC(2)N(4) coordination. The methyl groups are trans to each other in the octa-hedron surrounding the metal atom [C-Sn-C = 176.61?(12)°].

Bis(4,7-dichloro-1,10-phenanthroline-κN,N')bis-(dicyanamido-κN)copper(II).

Project description:In the title compound, [Cu(C(2)N(3))(2)(C(12)H(6)Cl(2)N(2))(2)], the Cu(II) atom is coordinated by two chelating 4,7-dichloro-1,10-phenanthroline (4,7-Cl-phen) ligands and two dicyanamide (dca) ligands in a cis arrangement, forming a distorted octa-hedral geometry. The equatorial plane is occupied by three N atoms from two 4,7-Cl-phen ligands and one N atom from a dca ligand at shorter Cu-N distances. Due to the Jahn-Teller effect, the axial positions are occupied by a 4,7-Cl-phen N atom and a dca N atom at longer Cu-N distances. The dca ligands are nearly planar, with a maximum deviations of 0.006 (1) Å. The crystal structure is stabilized by weak C-H⋯N hydrogen bonds, with cyanide N atoms as acceptors, and π-π inter-actions between adjacent phenyl rings [centroid-centroid distance = 3.725 (3) Å].

Bis(?(2)-4,7-dimethyl-4,7-diazadecane-1,10-dithiolato)trinickel(II) bis(perchlorate).

Project description:In the title compound, [Ni(3)(C(10)H(22)N(2)S(2))(2)](ClO(4))(2), the complex cation consists of a nickel(II) ion and two [Ni(C(10)H(22)N(2)S(2))] units with an N(2)S(2) tetra-dentate ligand, 3,3'-[1,2-ethane-diylbis(methyl-imino)]bis-(1-propane-thiol-ate). The central Ni(II) ion is located on a crystallographic inversion centre and is bound to the four S atoms of the two [Ni(C(10)H(22)N(2)S(2))] units to form a linear sulfur-bridged trimetallic moiety. The dihedral angle between the central NiS(4) plane and the terminal NiN(2)S(2) plane is 145.71?(5)°. In the [Ni(C(10)H(22)N(2)S(2))] unit, the two methyl groups on the chelating N atoms are cis to each other, and the two six-membered N,S-chelate rings adopt a chair conformation. The Ni-S bond lengths and the S-Ni-S bite angles in the central NiS(4) group are similar to those in the [Ni(C(10)H(22)N(2)S(2))] unit.

Dibromido(4,7-diazadecane-1,10-di-amine)-copper(II).

Project description:In the title compound, [CuBr(2)(C(8)H(22)N(4))], the Cu(II) atom is six-coordinate forming a distorted octa-hedral complex and is bonded to two axial bromide anions and four equatorial nitro-gen donors. The equatorial Cu-N bond distances range from 2.005 (8) to 2.046 (8) Å while the axial Cu-Br distances are 2.8616 (17) and 2.9402 (17) Å, thus the six-coordinate Cu complex shows the usual Jahn-Teller distortion. All amine hydrogen atoms participate in either inter- or intra-molecular hydrogen bonding to the Br anions.
