Diiodido(1,10-phenanthroline-κN,N')platinum(II).

ABSTRACT: In the title complex, [PtI(2)(C(12)H(8)N(2))], the Pt(2+) ion is four-coordinated in a slightly distorted square-planar environment by two N atoms of the chelating 1,10-phenanthroline ligand and two iodide ions. The nearly planar mol-ecules, with a maximum deviation of 0.170 (3) Å from the least-squares plane, are stacked in columns along the c axis with a Pt⋯Pt distance of 4.8510 (6) Å. In the column, π-π inter-actions between adjacent six-membered rings are present, the shortest centroid-centroid distance being 3.703 (5) Å.

Bromidobis(1,10-phenanthroline-κN,N')copper(II) dicyanamidate.

Project description:The title compound, [CuBr(C(12)H(8)N(2))(2)][N(CN)(2)], is formed of discrete [CuBr(phen)(2)](+) complex cations and uncoordinated [N(CN)(2)](-) anions (phen is 1,10-phenanthroline). The Cu atom is five-coordinated in a distorted trigonal-bipyramidal geometry by two phen mol-ecules and one bromide ligand, which coordinates in the equatorial plane at a distance of 2.5228 (4) Å and lying along with the Cu and the amide N atoms on a twofold rotation axis. The two axial Cu-N distances [1.9926 (15) Å] are slightly shorter than the two equatorial Cu-N bonds [2.0979 (15) Å]. The structure is stabilized by a weak C-H⋯N hydrogen bond, with a cyanide N atom of the dicyanamide ligand as an acceptor, and π-π inter-actions between nearly parallel phenyl and pyridine rings of two adjacent phen mol-ecules [centroid-centroid distance = 3.589 (1) Å], and between π electrons of the dicyanamide anion and the pyridine ring [N⋯Cg(pyridine) = 3.511 (3) Å; C-N⋯Cg(pyridine) = 80.2 (2)°].

Dichloridobis(1,10-phenanthroline-5,6-dione-κN,N')mercury(II).

Project description:In the title compound, [HgCl(2)(C(12)H(6)N(2)O(2))(2)], the Hg(II) atom is located on a twofold rotation axis and exists within a distorted octa-hedral geometry defined by a cis-Cl(2)N(4) donor set. Mol-ecules are connected into layers in the ac plane via extensive C-H⋯Cl contacts as each Cl atom forms two such inter-actions. Contacts between the layers are of the type C=O⋯π [O⋯centroid distance = 3.110 (8) Å].

Triaqua-(1,10-phenanthroline-κN,N')(sulfato-κO)zinc(II).

Project description:The Zn(II) atom in the title compound, [Zn(SO(4))(C(12)H(8)N(2))(H(2)O)(3)], is coordinated by one O atom from a sulfate dianion, two N atoms from a 1,10-phenanthroline mol-ecule and three water O atoms in an octa-hedral geometry. An intra-molecular O-H⋯O hydrogen bond occurs. Inter-molecular O-H⋯O hydrogen bonds generate a layer structure parallel to (001). There are weak C-H⋯O inter-actions within the layers.

Dibromido(2,9-dimethyl-1,10-phenanthroline-κN,N')mercury(II).

Project description:In the mol-ecule of the title compound, [HgBr(2)(C(14)H(12)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand and by two Br atoms. In the crystal structure, weak inter-molecular C-H⋯Br hydrogen bonds link the mol-ecules into chains along the b axis. There are π-π contacts between the phenanthroline rings [centroid-centroid distances = 3.806 (4), 3.819 (4), 3.739 (3), 3.690 (3), 3.619 (4) and 3.674 (3) Å].

Dichlorido(2,9-dimethyl-1,10-phenanthroline-κN,N')cobalt(II).

Project description:In the title compound, [CoCl(2)(C(14)H(12)N(2))], the Co(II) atom is four-coordinated in a distorted tetra-hedral geometry by two N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand and two Cl atoms. The Co atom and the phenanthroline unit are located on a mirror plane. The methyl H atoms are disordered about the mirror plane and areeach half-occupied. In the crystal structure, π-π inter-actions between the pyridine and benzene rings and between the pyridine rings [centroid-centroid distances = 3.8821 (9) and 3.9502 (10) Å, respectively] stabilize the structure.

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].

Diiodido(1,10-phenanthroline-5,6-dione-?N,N')mercury(II).

Project description:The Hg(II) atom in the title complex, [HgI(2)(C(12)H(6)N(2)O(2))], is tetra-hedrally coordinated by the N atoms of the chelating 1,10-phenanthroline-5,6-dione ligand and two I atoms. The range of tetra-hedral angles is broad, viz. 68.94?(17)° for the chelate angle to a wide 132.627?(15)° for the I-Hg-I angle. The ligand mol-ecule is non-planar with the O atoms lying 0.422?(5) and -0.325?(5)?Å out of the plane through the remaining atoms [r.m.s. deviation = 0.068?Å]. Mol-ecules are consolidated in the crystal packing by C-H?O inter-actions.

(Croconato-κO,O')bis-(1,10-phenanthroline-κN,N')zinc(II).

Project description:In the title compound, [Zn(C(5)O(5))(C(12)H(8)N(2))(2)], the Zn atom is in a slightly distorted octa-hedral environment. The mol-ecule lies across a twofold rotation axis, around which two 1,10-phenanthroline ligands are arranged. There are short contacts between the 1,10-phenanthroline groups and the O atoms of the croconate ligand, which probably stabilize the crystal structure via weak C-H⋯O interactions.

Project description:In the title compound, [CoCl(C(12)H(8)N(2))(H(2)O)(3)]Cl·H(2)O, the Co(II) ion is coordinated by two N atoms from the 1,10-phenanthroline ligand [Co-N = 2.125 (6) and 2.146 (6) Å], one chloride ligand [Co-Cl = 2.459 (2)Å] and three water mol-ecules [Co-O = 2.070 (5)-2.105 (5)Å] in a distorted octa-hedral geometry. Inter-molecular O-H⋯Cl and O-H⋯O hydrogen bonds form an extensive three-dimensional hydrogen-bonding network, which consolidates the crystal packing.

Project description:In the title compound, [Mg(SO(4))(C(12)H(8)N(2))(H(2)O)(3)], the Mg(II) centre exhibits a slightly distorted octa-hedral coordination environment defined by two N atoms from a 1,10-phenanthroline mol-ecule, one O atom from a sulfate dianion and three meridionally arranged O atoms from coordinated water mol-ecules. The crystal structure involves intra- and intermolecular O-H⋯O hydrogen bonds.
