Crystal structure of cis-diamminebis(nitrito-κN)platinum(II).

ABSTRACT: Single crystals of cis-[Pt(NO2)2(NH3)2], were obtained by means of hyper-saturation directly out of a plating electrolyte. The square-planar coordination environment of the divalent Pt(II) atom is formed by four N atoms belonging to two ammine and two monodentate nitrite ligands. The ligands adopt a cis configuration. The crystal structure contains stacks of close-packed mol-ecules which run parallel to [001]. There are nine crystallographically independent inter-molecular N-H⋯O hydrogen bonds, resulting in a hydrogen-bonded hxl-type framework in which each mol-ecule serves as an eight-connected node. Four of the nine distinct hydrogen bonds connect complexes which belong to the same close-packed column parallel to [001]. In contrast to the previously reported crystal structure of the trans isomer, the title structure does not display intra-molecular hydrogen bonding.

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

Project description:In the title complex, cis-[PtCl(2)(C(11)H(9)N)(2)], the Pt(II) ion is situated in a slightly distorted square-planar environment coordinated by two N atoms from two 2-phenyl-pyridine ligands and two Cl atoms. The two pyridyl planes are inclined with dihedral angles of 59.1 (2) and 61.84 (19)° with respect to the PtCl(2)N(2) plane. In the crystal, the complex mol-ecules display inter- and intra-molecular π-π stacking inter-actions, with centroid-centroid distances of 3.806 (5)-3.845 (5) Å, which form a one-dimensional column structure along the a 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.

Crystal structure of trans-di-chlorido-(4-nitro-aniline-κN (1))(piperidine-κN)platinum(II).

Project description:In the title complex, [PtCl2(C5H11N)(C6H6N2O2)], the Pt(II) metal atom displays a slightly distorted trans-PtN2Cl2 square-planar coordination geometry. The dihedral angle between the mean plane of the benzene and piperidine rings is 89.03 (3)°. In the crystal structure, inversion dimers are formed via N-H⋯Cl hydrogen-bond inter-actions, resulting in chains parallel to the [001] direction. The benzene rings within the chains show π-π stacking inter-actions [centroid-to-centroid distances of 3.801 (3) Å] and neighbouring chains inter-act via N-H⋯O hydrogen bonds.

cis-Dichloridobis(quinoline-κN)-platinum(II) nitro-methane monosolvate.

Project description:In the title compound, [PtCl(2)(C(9)H(7)N)(2)]·CH(3)NO(2), the Pt(II) cation is four-coordinated in an essentially square-planar environment by two N atoms from two quinoline ligands and two Cl(-) anions. One of the nearly planar quinoline ligands [maximum deviations = 0.042 (6) and 0.018 (7) Å] is almost perpendicular to the PtCl(2)N(2) unit [maximum deviation = 0.024 (3) Å], making a dihedral angle of 89.6 (1)°, whereas the other is slightly inclined to the central plane with a dihedral angle of 74.1 (1)°. The dihedral angle between the quinoline ligands is 88.3 (2)°. In the crystal, each solvent mol-ecule is linked to the metal complex by weak inter-molecular C-H⋯O hydrogen bonds.

Crystal structure of chlorido-(piperidine-κN)(quinoline-2-carboxyl-ato-κ(2) N,O)platinum(II).

Project description:The title compound, [Pt(C10H6NO2)Cl(C5H11N)], crystallizes with one mol-ecule in the asymmetric unit. The Pt(II) cation has a slightly distorted square-planar coordination environment defined by a chloride anion, the quinoline N atom and a carboxyl-ate O atom of the bidentate quinaldate ligand and a piperidine N atom. An intra-molecular C-H⋯Cl hydrogen bond occurs. In the crystal, mol-ecules are stacked into columns along the c axis by the formation of N-H⋯Cl and C-H⋯O hydrogen bonds.

Di-μ-nitrito-κO:O-bis-[bis-(1-ethyl-1H-imidazole-κN)(nitrito-κO)copper(II)].

Project description:In the structure of the title compound, [Cu(2)(NO(2))(4)(C(5)H(8)N(2))(4)], the asymmetric unit consists of two moieties containing one Cu ion, two nitrite ions and two 1-ethyl-1H-imidazole mol-ecules associated via weak Cu-O inter-actions. Each Cu(II) atom displays an elongted square-pyramidal CuN(2)O(3) coordination geometry with a slight tetra-hedral distortion in the basal plane. The dimeric units are linked into a three-dimensional network by C-H⋯O hydrogen bonds.

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].

cis-Dichlorido(dimethyl sulfoxide-κS)(N,N,N',N'-tetra-methyl-guanidine-κN'')platinum(II).

Project description:In the title compound, cis-[PtCl(2)(C(5)H(13)N(3))(C(2)H(6)OS)], the four-coordinate Pt(II) atom is bonded to one N atom of the N,N,N',N'-tetra-methyl-guanidine ligand, one dimethyl sulfoxide S atom and two chloride ligands, forming a cis-square-planar geometry. The bond lengths and angles of the N-Pt-Cl functionality are typical for imine dichloridoplatinum(II) complexes. The H atom of the imino group is oriented towards the O atom of the sulfoxide group of a neighboring mol-ecule and forms an N-H⋯O hydrogen bond.

Redetermination of cis-bis-(ethyl-ene-diamine-κ(2) N,N')bis-(nitrito-κN)cobalt(III) (ethyl-enediamine-κ(2) N,N')tetra-kis-(nitrito-κN)cobaltate(III) monohydrate.

Project description:The structure of the title compound, [Co(NO2)2(NH2CH2CH2NH2)2][Co(NO2)4(NH2CH2CH2NH2)]·H2O, was redetermined with a modern CCD-equipped diffractometer. In comparison with the original determination based on photographic data [Kushi et al. (1976 ▶). Inorg. Nucl. Chem. Lett. 12, 629-633], the current study allows the location of reliable postions for the H atoms and thus leads to better understanding of the inter-ionic and inter-molecular inter-actions. The crystal structure consists of an octa-hedrally coordinated cationic Co(III) complex ion, an octa-hedrally coordinated anionic Co(III) complex ion and a lattice water mol-ecule. The complex cation, complex anion and lattice water mol-ecule are connected by an intricate network of O-H⋯O and N-H⋯O hydrogen bonds, forming a three-dimensional structure.

Project description:In the binuclear title compound, [Cu(2)(NO(2))(4)(C(4)H(6)N(2))(4)], centro-symmetric-ally related complex mol-ecules are linked via weak Cu-O inter-actions, forming dimeric units.

The dihedral angle formed by the imidazole rings is 26.20 (10)°.
