Chlorido[6-phenyl-4-(p-tol-yl)-2,2'-bipyridyl-κN,N']platinum(II).

ABSTRACT: The asymmetric unit of the title compound, [Pt(C(23)H(17)N(2))Cl], contains two independent mol-ecules with distinct dihedral angles between the central pyridyl and methylbenzene rings [7.77 (2) and 24.07 (2)°]. Short inter-molecular distances [3.582 (6) and 3.600 (6) Å] between the outer pyridine and the PtNC(3) and PtN(2)C(2) rings, respectively, indicate the existence of π-π inter-actions, which link the mol-ecules into stacks along the a axis. The crystal structure is further stabilized by weak C-H⋯π inter-actions.

Project description:In the title compound, [Cu(C(4)H(8)NO(3))Cl(C(10)H(8)N(2))]·H(2)O, the Cu(II) atom is in a slightly distorted square-pyramidal coordination geometry with the basal plane defined by the two N atoms of the bipyridine ligand and the N and O atoms from the threoninate ion and the apical site occupied by the Cl atom.

Chlorido{5-chloro-2-[2-(methyl-sulfanyl)phenyl-diazen-yl]phenyl}-platinum(II).

Project description:The title compound, [Pt(C(13)H(10)ClN(2)S)Cl], contains a Pt atom tetra-coordinated by a benzene C, a diazene N, a Cl and an S atom in an approximately square-planar geometry.

{μ-N-[(Diphenyl-phosphino)meth-yl]pyridin-2-amine-κN:P}bis-{[2-(2,2'-bipyridin-6-yl)phenyl-κN,N',C]platinum(II)} bis-(perchlorate).

Project description:The title compound, [Pt(2)(C(16)H(11)N(2))(2)(C(18)H(17)N(2)P)](ClO(4))(2), contains two Pt(II) atoms, bridged by an N-[(diphenyl-phosphino)meth-yl]pyridin-2-amine (dppmp) ligand. One Pt atom is coordinated by one P atom from the dppmp ligand, and one C atom and two N atoms from a 6-phenyl-2,2'-bipyridine (pbpy) ligand in a square-planar geometry. The other Pt atom is coordinated by one N atom from the dppmp ligand, and one C atom and two N atoms from another pbpy ligand in a square-planar geometry. There are intra-molecular π-π inter-actions between the pbpy ligands, with a centroid-centroid distance of 3.62 (1) Å between two pyridyl rings. The oxygen atoms of both perchlorate anions are disordered, each over two different positions [occupanicies 0.49 (3)/0.51 (3) and 0.48 (2)/0.52 (2)].

Project description:The asymmetric unit of the title compound, [PtCl(4)(C(12)H(12)N(2))], contains one half-mol-ecule; a twofold rotation axis passes through the Pt atom and the mid-point of the C-C bond linking the two rings. The Pt(IV) atom is six-coordinated in an octa-hedral configuration by two N atoms of the 4,4'-dimethyl-2,2'-bipyridine ligand and four terminal Cl atoms. In the crystal structure, there are weak π-π inter-actions between pyridine rings, with a centroid-centroid distance of 4.365 (3) Å.

Chlorido(dimethyl sulfoxide-?S)[2-(2-pyrid-yl)phenyl-?N,C]platinum(II).

Project description:In the title compound, [Pt(C(11)H(8)N)Cl(C(2)H(6)OS)], the S atom of dimethyl sulfoxide is trans to the pyridyl N atom [Pt-S = 2.2181?(11)?Å] and the chlorido ligand is trans to the carbon donor of 2-(2-pyrid-yl)phenyl [Pt-Cl = 2.4202?(10)?Å]. The [2-(2-pyrid-yl)phen-yl]platinum(II) unit forms a one-dimensional stack along the c axis with two independent inter-planar separations of 3.44?(9) and 3.50?(2)?Å.

Crystal structure of {bis-[2-(3,5-di-methyl-pyrazol-1-yl-κN (2))eth-yl]amine-κN}chlorido-platinum(II) chloride dihydrate.

Project description:The title complex, [PtCl(C14H23N5)]Cl·2H2O, is isomorphous with the Pd(II) compound characterized previously [Mendoza, Bernès & Mendoza-Díaz (2006 ▶). Acta Cryst. E62, m2934-m2936]. The angle between pyrazole mean planes in the main ligand is 88.3 (4)°, similar to that observed in the Pd(II) analogue [87.62 (11)°]. This tridentate ligand adopts a conformation approximating a twofold symmetry, allowing its coordination to the metal atom, together with a chloride ligand, in an almost perfect square-planar geometry. A chloride anion and two water mol-ecules in the asymmetric unit form a hydrogen-bonded network connected to the complex mol-ecules in the crystal via the NH amine groups, forming chains along [100].

(2,2'-Bipyridyl-κN,N')tetra-kis(4-methyl-benzoato-κO)manganese(II).

Project description:In the title mononuclear complex, [Mn(C(8)H(7)O(2))(4)(C(10)H(8)N(2))], the Mn(II) atom lies on a twofold rotation axis and has a distorted octa-hedral coordination geometry defined by four O atoms from four 4-methyl-benzoate ligands and two N atoms from one 2,2'-bipyridyl ligand. The crystal structure is stabilized by inter-molecular hydrogen bonds and π-π stacking inter-actions [the centroid-centroid distance between the parallel pyridyl ring of a 2,2'-bipyridyl and benzene ring of a 4-methylbenzoic group of a neighboring complex is 3.839 (2) Å].

(2,2'-Bipyridine-κN,N')chlorido[4'-(2,5-dimethoxy-phen-yl)-2,2':6',2''-terpyridine-κN,N',N'']ruthenium(II) hexa-fluorido-phosphate acetonitrile monosolvate.

Project description:In the title compound, [RuCl(C(10)H(8)N(2))(C(23)H(19)N(3)O(2))]PF(6)·CH(3)CN, the ligand environment about the Ru(II) atom is distorted octa-hedral, with the substituted terpyridyl ligand coordinated in a meridional fashion, the bipyridyl ligand coordinated in a cis fashion and the Cl atom trans to one of the bipyridyl N atoms. The Ru-N distances are in the range 2.036 (2)-2.084 (2) Å with the exception of the central Ru-N bond from the terpyridyl ligand, which is shorter [1.9503 (19) Å], as expected. The pendant dimethoxy-phenyl substituent is not coplanar with the terpyridyl unit; the dihedral angle between the central pyridyl ring and the benzene ring is 46.72 (11)°. The anion is disordered equally over two positions around an F-P-F bond axis.

cis-Dibromidobis(2-phenyl-pyridine-κN)platinum(II).

Project description:In the title complex, [PtBr(2)(C(11)H(9)N)(2)], the Pt(II) ion has a distorted cis-Br(2)N(2) square-planar coordination geometry defined by two N atoms from two 2-phenyl-pyridine (ppy) ligands and two Br(-) anions. The ppy ligands are not planar, the dihedral angles between the pyridine and benzene rings being 49.0 (3) and 47.3 (3)°. In the crystal, the complex mol-ecules are stacked in columns along the a axis. In the columns, there are numerous intra- and inter-molecular π-π inter-actions between the six-membered rings, the shortest ring centroid-centroid distance being 3.774 (6) Å.

Project description:The crystal structure (150 K) of the racemic title compound, [PtCl2(C44H32P2)]·3CH3CN, has been determined. The asymmetric unit comprises a single mol-ecule of the title compound co-crystallized with three aceto-nitrile solvent mol-ecules. Four mol-ecules are observed in the unit cell, with R and S enanti-omers present in a 2:2 ratio. Evidence of intra-molecular π-stacking is observed with no discernable inter-molecular inter-actions.
