Crystal structure of (μ-1,4-di-carb-oxy-butane-1,4-di-carboxyl-ato)bis-[bis-(tri-phenyl-phosphane)silver(I)] di-chloro-methane tris-olvate.

ABSTRACT: The mol-ecular structure of the tetra-kis(tri-phenyl-phosphan-yl)disilver salt of butane-1,1,4,4-tetra-carb-oxy-lic acid, [Ag2(C8H8O8)(C18H15P)4]·3CH2Cl2, crystallizes with one and a half mol-ecules of di-chloro-methane in the asymmetric unit. The coordination complex exhibits an inversion centre through the central CH2-CH2 bond. The Ag(I) atom has a distorted trigonal-planar P2O coordination environment. The packing is characterized by inter-molecular T-shaped π-π inter-actions between the phenyl rings of the PPh3 substituents in neighbouring mol-ecules, forming a ladder-type superstructure parallel to [010]. These ladders are arranged in layers parallel to (101). Intra-molecular hydrogen bonds between the OH group and one O atom of the Ag-bonded carboxyl-ate group results in an asymmetric bidendate coordination of the carboxyl-ate moiety to the Ag(I) ion.

Project description:In the centrosymmetric dinuclear copper(I) complex cation of the title compound, [Cu2(C28H28P2)3](PF6)2·2C4H10O, the Cu(I) atom is bonded to three P atoms of two butane-1,4-diylbis(di-phenyl-phosphane) (dppb) ligands with a triangular coordination geometry. One of these P atoms belongs to a bridging dppb ligand [Cu-P = 2.2381 (5) Å] and two belong to a chelating dppb ligand [Cu-P = 2.2450 (6) and 2.2628 (5) Å]. The bridging dppb ligand lies on an inversion centre. In the crystal, the cation and the PF6 (-) anion are linked by C-H⋯F inter-actions, forming a tape along [110]. The cation and the diethyl ether solvent mol-ecule are also linked by a C-H⋯O inter-action.

(Butane-1,4-di-yl)(trimethyl-phosphane-?P)[tris-(3,5-dimethyl-pyrazol-1-yl-?N (2))hydro-borato]iridium(III).

Project description:In the mononuclear title iridium(III) complex, [Ir(C4H8)(C15H22BN6)(C3H9P)], which is based on the [tris-(3,5-dimethyl-pyrazol-1-yl)hydro-borato]iridium moiety, Ir[Tp(Me2)], the Ir(III) atom is coordinated by a chelating butane-1,4-diyl fragment and a trimethyl-phosphane ligand in a modestly distorted octa-hedral coordination environment formed by three facial N, two C and one P atom. The iridium-butane-1,4-diyl ring has an envelope conformation. This ring is disordered because alternately the second or the third C atom of the butane-1,4-diyl fragment function as an envelope flap atom (the occupancy ratio is 1:1). In the crystal, mol-ecules are organized into densely packed columns extending along [101]. Coherence between the mol-ecules is essentially based on van der Waals inter-actions.

Poly[μ-aqua-[μ-1,1'-(butane-1,4-di-yl)diimidazole]bis-(μ(4)-naphthalene-1,4-dicarboxyl-ato)dicadmium(II)].

Project description:In the title compound, [Cd(2)(C(12)H(6)O(4))(2)(C(10)H(14)N(4))(H(2)O)](n), the coordination polyhedron around each Cd(II) ion is a distorted CdNO(5) octa-hedron.

The naphthalene-1,4-dicarboxyl-ate and L ligands bridge the metal centres, forming a three-dimensional framework, which is consolidated by O-H⋯O hydrogen bonds.

Bis(butane-1,4-diammonium) di-?-oxido-bis[trifluoridooxidomolybdate(V)] monohydrate.

Project description:The title compound, (C4H14N2)2[Mo2O4F6]·H2O, was obtained by solvothermal reaction at 443?K for 72?h from a mixture of MoO3, HF, 1,4-diamino-butane (dab), water and ethyl-ene glycol. The structure consists of [Mo2O4F6](4-) anionic dimers containing strongly distorted MoO3F3 octa-hedra (with twofold symmetry), diprotonated dab cations and water mol-ecules (twofold symmetry) in the ratio 1:2:1. The cohesion of the three-dimensional structure is ensured through N-H?O, N-H?F and O-H?F inter-actions.

Butane-1,4-diammonium bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II) trihydrate.

Project description:In the title compound, (C(4)H(14)N(2))[Cu(C(7)H(3)NO(4))(2)]·3H(2)O or (bdaH(2))[Cu(pydc)(2)]·3H(2)O (where bda is butane-1,4-diamine and pydcH(2) is pyridine-2,6-dicarboxylic acid), the Cu(II) atom is coordinated by four O atoms [Cu-O = 2.0557?(16)-2.3194?(16)?Å] and two N atoms [Cu-N = 1.9185?(18) and 1.9638?(18)?Å] from two chelating rings of the pydc(2-) anions, which act as tridentate ligands. The geometry of the resulting CuN(2)O(4) coordination can be described as distorted octa-hedral. The the two pydc(2-) fragments are almost perpendicular to one another [77.51?(11)°]. To balance the charges, two centrosymmetric protonated butane-1,4-diammonium, (bdaH(2))(2+) cations are present. In the crystal structure, extensive O-H?O, N-H?O and C-H?O hydrogen bonds [D?A = 2.720?(2)-3.446?(3)?Å], ion pairing, C-O?? [O?? = 3.099?(2)?Å] and ?-? stacking inter-actions between the pydc(2-) rings [centroid-centroid distance = 3.5334?(15)?Å] contribute to the formation of a three-dimensional supra-molecular structure.
