Bis(μ-5-diisopropyl-amino-1,2,3,4-tetra-zolido-κN:N)bis-[(triisopropyl-phosphane)copper(I)].

ABSTRACT: In the binuclear centrosymmetric crystal structure of the title compound, [Cu(2)(C(7)H(14)N(5))(2)(C(9)H(21)P)(2)], all atoms except those of the isopropyl groups are approximately co-planar. The Cu(II) atom is in a distorted trigonal-planar CuN(2)P coordination. Bond angles around the amino N atom suggest sp(2) hybridization. Several intra-molecular C-H⋯N inter-actions are present involving tetra-zolate N atoms.

Bis[5-(pyridin-2-yl-κN)tetra-zolido-κN (1)]copper(II).

Project description:In the title complex, [Cu(C6H4N5)2], the Cu(II) ion lies on an inversion center and is coordinated by two chelating 5-(pyridin-2-yl)tetra-zolide ligands in a slightly distorted square-planar coordination geometry. In the crystal, π-π stacking inter-actions, with centroid-centroid distances in the range 3.4301 (14)-3.4387 (13) Å, link the complex mol-ecules along [101].

Bis(?-diisopropyl-phosphanido-?(2)P:P)bis-[hydrido(triisopropyl-phosphane-?P)platinum(II)].

Project description:In the centrosymmetric mol-ecular structure of the title compound [Pt(2)(C(6)H(14)P)(2)H(2)(C(9)H(21)P)(2)], each Pt(II) atom is bound on one side to a phosphane ligand (PiPr(3)) and a hydrido ligand. On the other side, it is bound to two phosphanide ligands (?-PiPr(2)), which engage a bridging position between the two Pt(II) atoms, forming a distorted square-planar structure motif. The Pt?Pt distance is 3.6755?(2)?Å. A comparable mol-ecular structure was observed for bis-(?-di-tert-butyl-phosphanido)bis-[hydrido(triethyl-phosphane)platinum(II)] [Itazaki et al. (2004 ?). Organometallics, 23, 1610-1621].

Project description:The title compound, {[Cu(2)I(2)(C(12)H(8)N(6))(C(18)H(15)P)(2)]·2CH(3)CN}(n), contains centrosymmetric dinuclear Cu(2)I(2)(PPh(3))(2) units bridged by 3,6-bis-(4-pyrid-yl)-1,2,4,5-tetra-zine ligands lying also across crystallographic inversion centers, giving a chain structure in the ab plane. The distorted tetra-hedral Cu(I) atoms in the dinuclear unit are coordinated by two bridging iodide anions, one pyridine N atom from the substituted tetra-zine ligand and one terminal triphenyl-phosphine P-atom donor. The Cu⋯Cu distance is 2.8293 (12) Å, implying a weak Cu⋯Cu inter-action.

Project description:The title complex, {[Cu(2)(C(10)H(8)N(2))(C(25)H(22)P(2))(2)](BF(4))(2)·2.5CH(2)Cl(2)}(n), contains chains of Cu(I) centres bridged alternately by two (diphenyl-phosphino)methane (dppm) and 4,4'-bipyridine (bpy) ligands. Each Cu(I) atom is coordinated by one N atom of 4,4'-bipyridine (bpy) and two P atoms of two (diphenyl-phosphino)methane (dppm) ligand, and has a trigonal-planar coordination geometry. There is an inversion centre midway between each pair of adjacent Cu atoms. The distance of two Cu(I) atoms separated by two (diphenyl-phosphino)methane bridging ligands is 3.732 (3) Å, and 4,4'-bipyridine 11.138 (5) Å.

Tetra-aqua-bis-(tetra-zolido-?N)magnesium.

Project description:In the crystal structure of the title compound, [Mg(CHN(4))(2)(H(2)O)(4)], the Mg(II) atom is six-coordinated by two N atoms from two tetra-zolide anions and four O atoms from four coordinated water mol-ecules in a slightly distorted octa-hedral geometry. The Mg atom is located on centres of inversion whereas the tetra-zolide anion and the water mol-ecules occupy general positions. The crystal packing is stabilized by intermolecular O-H?N hydrogen bonding between the tetra-zolide anions and the coordinated water mol-ecules.

The Cu atom is 0.216 Å out of the plane of the four O atoms.

Di-μ-chlorido-bis-[dichlorido(3,3',5,5'-tetra-methyl-4,4'-bipyrazol-1-ium-κN)copper(II)] dihydrate.

Project description:The structure of the centrosymmetric title compound, [Cu(2)Cl(6)(C(10)H(15)N(4))(2)]·2H(2)O, consists of a dimeric [{(HMe(4)bpz)CuCl(3)}(2)] unit (HMe(4)bpz is 3,3',5,5'-tetra-methyl-4,4'-bipyrazol-1-ium) with two solvent water molecules. Each [HMe(4)bpz](+) cation is bonded to a CuCl(3) unit through a Cu-N dative bond, effectively making square-planar geometry at the Cu atom. Two of these units then undergo a face-to-face dimerization so that the Cu atoms have a Jahn-Teller distorted square-pyramidal geometry with three chlorides and an N atom in the basal plane and one chloride weakly bound in the apical position. Several N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds form a three-dimensional network.

catena-Poly[{μ-cyanido-bis-[(4,4'-dimethyl-2,2'-bipyridine-κN,N')copper(I)]}-μ-cyanido-copper(I)-μ-cyanido].

Project description:In the title compound, [Cu(3)(CN)(3)(C(12)H(12)N(2))(2)], two 2,2'-bipyridine N,N'-chelated Cu(I) atoms are linked by a cyanide bridge that lies about a center of inversion; the Cu(I) atom exists in a tetra-hedral coordination geometry. This dinuclear entity is linked to another Cu(I) atom that lies on a twofold rotation axis by another cyanide bridge, these bridges giving rise to the formation of a linear chain motif.

Project description:In the polymeric title copper(II) compound, [Cu(CHO(2))(2)(C(8)H(6)N(2))](n), both formato ligands are O-bidentate anions and act as bridging ligands, creating a planar polymeric arrangement. The slightly distorted square-pyramidal coordination around Cu(II) comprises four O atoms from two different formate anions as the base and a quinoxaline mol-ecule in the apical position.
