Dichloridotetra-kis-(diniconazole)nickel(II).

ABSTRACT: In the title compound, [NiCl(2)(C(15)H(17)Cl(2)N(3)O)(4)], the Ni atom lies on an inversion center and has an axially extended trans-NiCl(2)N(4) octa-hedral geometry arising from its coordination by four diniconazole [systematic name: (E)-(RS)-1-(2,4-dichloro-phen-yl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol] ligands and two chloride ions. In the crystal, O-H⋯Cl hydrogen bonds link the mol-ecules into [100] chains.

Dichloridotetra-kis-(diniconazole)cobalt(II).

Project description:In the crystal structure of the title compound, [CoCl(2)(C(15)H(17)Cl(2)N(3)O)(4)], the Co(II) cation lies on an inversion center and has a slightly distorted octa-hedral coordination geometry. The equatorial positions are occupied by four N atoms from four diniconazole [systematic name: (E)-(RS)-1-(2,4-dichloro-phen-yl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pent-1-en-3-ol] ligands. The axial sites are occupied by two Cl(-) anions. In the two independent organic ligands, the triazole ring is oriented at dihedral angles of 18.28?(14) and 32.15?(14)° with respect to the dichloro-phenyl ring. Inter-molecular O-H?Cl hydrogen bonds consolidate the crystal packing.

Dichloridotetra-kis-(1H-1,2,4-triazole-?N(4))copper(II).

Project description:The central Cu(II) atom of the molecular title complex, [CuCl(2)(C(2)H(3)N(3))(4)], is situated on a site with symmetry 2.22. It is six-coordinated in an elongated octa-hedral geometry, with the equatorial plane defined by four N atoms of four 1,2,4-triazole ligands and the axial positions occupied by two Cl atoms situated on a twofold axis. The mol-ecules are connected via N-H?Cl hydrogen bonds and the crystal consists of two inter-penetrating three-dimensional hydrogen-bonded frameworks.

cis-Dichloridotetra-kis-(trimethyl-phosphane-?P)ruthenium(II) benzene disolvate.

Project description:The title compound, cis-[RuCl(2)(C(3)H(9)P)(4)]·2C(6)H(6), contains a complex mol-ecule with a crystallographic mirror plane passing through the Ru(II) atom, the two cis-disposed Cl ligands and two P atoms of the two cis-disposed P(CH(3))(3) ligands. The Ru(II) atom adopts a distorted octa-hedral RuCl(2)P(4) coordination geometry with the two trans-disposed P atoms occupying the axial positions. The packing of the structure is accomplished through non-classical C-H?Cl hydrogen bonds between the benzene solvent mol-ecule and one of the Cl ligands.

Hexa-kis-(thio-urea-?S)nickel(II) nitrate: a redetermination.

Project description:A preliminary X-ray study of the title mol-ecular salt, [Ni(CH(4)N(2)S)(6)](NO(3))(2), has been reported twice previously, by Ma?ar [Acta Cryst. (1961), 14, 894] and Rodriguez, Cubero, Vega, Morente & Vazquez [Acta Cryst. (1961), 14, 1101], using film methods. We confirm the previous studies, but to modern standards of precision and with all H atoms located. The central Ni atom (site symmetry ) of the dication is octa-hedrally coordinated by six S-bound thio-urea mol-ecules. The crystal structure is stabilized by intra- and inter-molecular N-H?S and N-H?O hydrogen bonds.

Project description:In the title complex, [Ni(CH(3)CN)(2)(C(3)H(4)N(2))(4)](NO(3))(2), the cation lies on an inversion center and adopts an octa-hedral coordination geometry about the Ni atom. The two acetonitrile ligands are in a trans conformation. N-H?O hydrogen bonds between cations and anions link the complex mol-ecules into one-dimensional chains running parallel to [100].

Project description:The mol-ecule of the title compound, [Ni(C(68)H(76)N(4)O(4))], is located on a crystallographic inversion center. The Ni-N distances within the square-shaped coordination environment are 1.951?(2) and 1.954?(2)?Å. Three terminal C atoms in one of the hexyl groups are disordered over two sets of sites, with site-occupancy factors of 0.615?(13) and 0.385?(13).

Hexa-kis-(N,N'-dimethyl-thio-urea-?S)nickel(II) nitrate.

Project description:The title complex salt, [Ni(C(3)H(8)N(2)S)(6)](NO(3))(2), consists of an [Ni(Dmtu)(6)](2+) (Dmtu is N,N'-dimethyl-thio-urea) dication and two nitrate counter-anions. The Ni(II) atom (site symmetry ) is coordinated by the S atoms of six Dmtu ligands within a slightly distorted octa-hedral environment. The crystal structure is characterized by weak intra-molecular N-H?S inter-actions and by inter-molecular N-H?O hydrogen bonds involving the nitrate anion (site symmetry 3.). These inter-molecular inter-actions lead to the formation of two-dimensional networks lying parallel to the ab plane. The networks are linked via non-classical inter-molecular C-H?O hydrogen bonds, forming a three-dimensional arrangement.
