(2-{[4-(Chlorido-mercur-yl)phen-yl]imino-meth-yl}pyridine-κ(2) N,N')di-iodido-mercury(II) dimethyl sulfoxide monosolvate.

ABSTRACT: The title dimethyl sulfoxide solvate, [Hg2(C12H9ClN2)I2]·C2H6OS, features tetra-hedrally and linearly coordinated Hg(II) atoms. The distorted tetrahedral coordination sphere is defined by chelating N atoms that define an acute angle [69.6 (3)°] and two I atoms that form a wide angle [142.80 (4)°]. The linearly coordinated Hg(II) atom [177.0 (4)°] exists with a donor set defined by C and Cl atoms. Secondary inter-actions are apparent in the crystal packing with the tetra-hedrally and linearly coordinated Hg(II) atoms expanding their coordination environments by forming weak Hg⋯I [3.772 (7) Å] and Hg⋯O [2.921 (12) Å] inter-actions, respectively. Mercury-containing mol-ecules stack along the a axis, are connected by π-π inter-actions [inter-centroid distance between pyridine and benzene rings = 3.772 (7) Å] and define channels in which the dimethyl sulfoxide mol-ecules reside. The latter are connected by the aforementioned Hg⋯O inter-actions as well as C-H⋯I and C-H⋯O inter-actions, resulting in a three-dimensional architecture.

(4-tert-Butyl-pyridine)-chlorido[hydro-tris-(3,5-dimethyl-pyrazol-1-yl)borato]nitro-sylmolybdenum(I) dichloro-methane monosolvate.

Project description:In the title compound, [Mo(C(15)H(22)BN(6))Cl(NO)(C(9)H(13)N)]·CH(2)Cl(2), the Mo(I) atom adopts a distorted MoClN(5) octa-hedral geometry with the hydro-tris-(3,5-dimethyl-pyrazol-yl)borate anion in an N,N',N''-tridentate tripodal (facial) coordination mode. A 4-tert-butyl-pyrine ligand, chloride anion and a nitrosyl cation complement the coodination of the Mo(I) atom and an intra-molecular C-H?Cl hydrogen bond helps to stabilize the configuration of the complex mol-ecule. The packing is stabilized by an inter-molecular C-H?Cl hydrogen bond involving the complex mol-ecule and the CH(2)Cl(2) solvent mol-ecule.

Pyrimethaminium 2-{[4-(tri-fluoro-meth-yl)phen-yl]sulfan-yl}benzoate dimethyl sulfoxide monosolvate.

Project description:In the cation of the title solvated mol-ecular salt, C12H14ClN4 (+)·C14H8F3O2S(-)·C2H6OS [systematic name of the cation: 2,4-di-amino-5-(4-chloro-phen-yl)-6-ethyl-pyrimidin-1-ium], the dihedral angle between the planes of the pyrimidinium and 4-chloro-phenyl rings is 77.2?(5)°. In the anion, the planes of the benzene rings are twisted with respect to each other by 71.5?(5)°. Disorder was modelled for the dimethyl sulfoxide solvent mol-ecule over two set of sites in a 0.7487?(13):0.2513?(13) ratio. In the crystal, the cations are linked by inversion-generated pairs of N-H?N hydrogen bonds, with an R 2 (2)(8) graph-set motif. The cation donates two N-H?O hydrogen bonds to the anion, also generating an R 2 (2)(8) loop. These inter-actions, along with cation-solvent N-H?O hydrogen bonds, and cation-anion C-H?F, solvent-anion C-H?O and C-H?F inter-actions, result in a three-dimensional network.
