Bis(tetraphenylphosphonium) tetra-cyanido-nitridochromate(V) dihydrate.

ABSTRACT: In the title compound, (C(24)H(20)P)(2)[Cr(CN)(4)(N)]·2H(2)O, the complex anion exhibits a square-based pyramidal geometry around the central Cr(V) atom, which is coordinated by a nitride ligand in the apical position and by four cyanide ligands in the equatorial plane. The chromium atom is located 0.4493?(13)?Å out of the plane formed by the ligating C atoms of the cyanide ligands. The water mol-ecules of crystallization form inter-molecular O-H?N hydrogen bonds to the N atoms of two cyanide ligands of neighbouring complex anions, forming an infinite hydrogen-bonded chain parallel to [011] of water mol-ecules and [Cr(N)(CN)(4)](2-) anions. The terminal nitride ligands are not engaged in inter-molecular inter-actions.

Tetra-potassium hepta-cyanido-molybdate(III) dihydrate.

Project description:The asymmetric unit of the title compound, K(I) (4)[Mo(III)(CN)(7)]·2H(2)O, consists of one [Mo(CN)(7)](4-) anion, four K(+) cations, and two water mol-ecules. The [Mo(III)(CN)(7)](4-) anion has a seven-coordinated capped-trigonal-prismatic coordination geometry. The site-occupancy factors of the disordered water mol-ecules were set at 0.90, 0.60 and 0.50. The H-atom positions could not be determined for two of the water mol-ecules. The H atoms of the water with a site-occupancy factor of 0.90 were refined using O-H and H⋯H distance restraints.

[(Triethyl-ene-tetra-mine)copper(II)]-?-cyanido-?(2) N:C-[bis(cyanido-?C)copper(I)].

Project description:The title compound, [Cu2(CN)3(C6H18N4)] or [Cu(trien)(CN)Cu(CN)2], where trien is triethyl-ene-tetra-mine, is a mixed-valence complex crystallizing as discrete mol-ecules, with Cu(I) and Cu(II) ions linked by a bridging cyanide group. The Cu(II) ion is in a square-pyramidal coordination environment, with the N atoms of the tetra-dentate trien ligand occupying the basal positions and Cu-N bond lengths in the range 2.028?(4)-2.047?(4)?Å. An N-bonded cyanide group is in the apical position, with a slightly longer Cu-N bond length of 2.127?(4)?Å. The Cu(I) ion exhibits a trigonal-planar coordination geometry, bonded to the C atoms of the bridging cyanide group and two terminal cyanide groups with Cu-C bond lengths in the range 1.925?(4)-1.948?(5)?Å. In the crystal, hydrogen bonding involving the tertiary N-H groups of the trien ligand and N atoms of symmetry-related terminal cyanide groups links mol-ecules into a ribbon extending in the b-axis direction.

Poly[bis[3,10-bis(2-hydroxyethyl)-1,3,5,8,10,12-hexa-azacyclo-tetra-deca-ne]tetra-μ-cyanido-tetracyanidodicopper(II)molybdenum(IV)] tetra-hydrate].

Project description:In the title complex, {[Cu(2)Mo(CN)(8)(C(12)H(30)N(6)O(2))(2)]·4H(2)O}(n), the polyhedron around Mo has site symmetry with a distorted square-antiprismatic shape, while the Cu atom (2 symmetry) is in a distorted axially elongated octa-hedral coordination environment. The uncoordinated water molecule is disordered over three sites with occupancies of 0.445 (7), 0.340 (7) and 0.215 (7). Mo and Cu atoms acting as basic components are connected by an Mo-CN-Cu-NC-Mo- linkage to form a distorted diamond-like network. Additional hydrogen bonding between the N-H groups and the water molecules stabilizes this arrangement.

Tetra-aqua-bis(orotato-?O)cobalt(II) dihydrate.

Project description:In the title Co(II) complex, [Co(C(5)H(3)N(2)O(4))(2)(H(2)O)(4)]·2H(2)O, the Co(II) ion is located on an inversion center and is coordinated by two orotate (2,6-dioxo-1,2,3,6-tetrahydropyrimidine-4-carboxylate) anions and four water mol-ecules in a slightly distorted octa-hedral geometry. The dihedral angle between the carboxyl-ate group and the attached orotate ring is 1.2?(3)°. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. ?-? contacts between the orotate rings [centroid-centroid distances = 3.439?(2) and 3.438?(2)?Å] further stabilize the structure.

Tetra-aqua-bis-(piperazin-1-ium)cobalt(II) bis-(sulfate) dihydrate.

Project description:In the centrosymmetric title compound, [Co(C4H11N2)2(H2O)4](SO4)2·2H2O, the Co(II) atom is coordinated in a distorted octa-hedral geometry by four water O atoms and two piperazinium N atoms. These four water O atoms define an equatorial plane with a maximum deviation of 0.0384 (1) Å while the two piperazinium N atoms complete the octa-hedron in the axial positions. Neighboring complex mol-ecules and sulfate anions are connected through an extensive network of N-H⋯O and O-H⋯O hydrogen bonds, which link the different chemical species into layers in the ab plane. Additional Owater-H⋯O hydrogen bonds involving the non-coordinating water mol-ecules and C-H⋯O inter-actions connect these layers into a three-dimensional supra-molecular structure.

Tetra-imidazolium piperazinediium bis-(benzene-1,3,5-tricarboxyl-ate) dihydrate.

Project description:During the crystallization of the title compound, 4C(3)H(5)N(2) (+)·C(4)H(12)N(2) (+)·2C(9)H(3)O(6) (3-)·2H(2)O, the acidic protons were transferred to the imidazole and piperazine N atoms, forming the final 4:1:2:2 hydrated mixed salt. The mean planes of the three carboxyl-ate groups in the anion are twisted with respect to the the central benzene ring, making dihedral angles of 13.5?(1), 14.5?(1) and 16.9?(1)°. In the crystal, the component ions are linked into a three-dimensional network by a combination of inter-molecular N-H?O, O-H?O and weak C-H?O hydrogen bonds. Further stabilization is provided by ?-? stacking inter-actions with centroid-centroid distances of 3.393?(2)?Å and weak C=O?? inter-actions [O-centroid = 3.363?(2)?Å].
