Tetra-ethyl-ammonium tricarbonyl-chlorido(quinoxaline-2-carboxyl-ato-?N,O)rhenate(I).

ABSTRACT: In the title compound, (C(8)H(20)N)[Re(C(9)H(5)N(2)O(2))Cl(CO)(3)], the Re(I) atom is coordinated facially by three carbonyl groups, the bidentate quinoxaline-2-carbaldehyde ligand and a chloride atom, forming a distorted octahedral geometry.. The crystal packing is controlled by C-H?O hydrogen bonding and ?-? stacking inter-actions involving the benzene rings, with a centroid-centroid distance of 3.4220?(1)?Å.

Tetra-ethyl-ammonium tricarbonyl-chlorido(isoquinoline-1-carboxyl-ato-?N,O)technetate(I).

Project description:The asymmetric unit of the title compound, (C(8)H(20)N)[Tc(C(10)H(6)NO(2))Cl(CO)(3)], consists of two crystallographically independent technetium complexes related via a pseudo-inversion centre and two tetra-ethyl-ammonium cations. The Tc atoms have slightly distorted octa-hedral coordination geometries, and they are linked with the cations by inter-molecular C-H?O and C-H?Cl hydrogen-bonding contacts, forming two-dimensional columns, which lie approximately parallel to (001) in the crystal structure. The isochinolate (isoquinoline-1-carboxyl-ate) ligands link the columns by partial ?-? stacking [centroid-centroid distance 4.3733?(11)?Å], forming a three-dimensional network structure.

Tetra-ethyl-ammonium (acetyl-acetonato)bromidotricarbonyl-rhenate(I).

Project description:In the title compound, (C(8)H(20)N)[ReBr(C(5)H(7)O(2))(CO)(3)], the Re(I) atom in the rhenate anion is surrounded by three carbonyl ligands orientated in a facial arrangement, a bromide ligand and an acetyl-acetonate ligand, leading to a distorted octa-hedral ReC(3)BrO(2) coordination with a O-Re-O bite angle of 85.66?(7)°. An array of C-H?O and C-H?Br hydrogen-bonding inter-actions between the cations and the surrounding rhenate anions stabilize the crystal structure.

Tetra-ethyl-ammonium bromidotricarbon-yl(tropolonato)rhenate(I).

Project description:In the title salt, (C(8)H(20)N)[ReBr(C(7)H(5)O(2))(CO)(3)], the Re(I) atom is octa-hedrally surrounded by three facially orientated carbonyl ligands, one bidendate tropolonate ligand and a bromide ligand. The small O-Re-O bite angle of 74.88 (12)° leads to a distortion of the octa-hedral coordination sphere. The bromide ligand and the axial carbonyl ligand are substitutionally disordered over two positions in a 0.922 (3):0.078 (3) ratio. An array of C-H⋯O and C-H⋯Br hydrogen-bonding inter-actions between the cations and neighbouring rhenate anions stabilizes the crystal packing.

Tetra-ethyl-ammonium dicyanidobis(ethane-1,2-dithiol-ato)tetra-?(3)-sulfido-dimolybdenum(V)dicopper(I).

Project description:The title compound, (C(8)H(20)N)(2)[Cu(2)Mo(2)(C(2)H(4)S(2))(2)(CN)(2)S(4)], is a sulfide-bridged tetranuclear complex in which the complex anion comprises one [(edt)(2)Mo(2)S(2)(?-S)(2)](2-) unit (edt = ethanedithiol-ate) and two CuCN units joined through six Cu-?(3)-S bonds, thus forming a cubane-like [Mo(2)S(4)Cu(2)] core. There are two independent cation-anion complex entities in the asymmetric unit. Bond distances are normal for this type of complex [ranges: Mo-S = 2.193?(2)-2.390?(2); Cu-S = 2.266?(2)-2.470?(2); Cu-C = 1.899?(7)-1.911?(9)?Å].

Crystal structure of the thermochromic bis-(di-ethyl-ammonium) tetra-chlorido-cuprate(II) complex.

Project description:In the structure of the title complex salt, (Et2NH2)2[CuCl4], the asymmetric unit consists of four unique di-ethyl-ammonium cations and three unique tetra-chlorido-cuprate anions. Two of the three anions are located with their copper atoms on independent crystallographic twofold axes, while the remaining tetra-chlorido-cuprate is located at a general position of the ortho-rhom-bic space group P21212. Two of the three Cu atoms adopt a distorted square-planar/disphenoidal geometry and the third Cu atom has a regular square-planar coordination environment. The di-ethyl-ammonium cations form an extensive hydrogen-bonded network through N-H⋯Cl inter-actions with the tetra-chlorido-cuprate anions, resulting in a two-dimensional sheet-like hydrogen-bonded network parallel to the ab direction. The complex was observed to undergo a color shift from deep green at room temperature to pale yellow at temperatures above 328 K.
