The title compound, [Ag(C(7)H(2)Br(3)O(2))(C(18)H(15)P)(3)], a silver(I) derivative of 3,5,7-tribromo-tropolone, has three triphenyl-phosphine ligands coordinated to the silver centre, whereas the 3,5,7-tribromo-tropolonate anion coordinates as a bidentate ligand. The compound is an example of a five-coordinate silver complex containing a bidentate ligand.
The title compound, [Rh(C(17)H(15)Cl(2)N(2))(CO)(2)], is a rhodium(I) derivative of a β-diketiminato moiety. It is an example of a new type of β-diketiminate derivative that has not yet been characterized via solid-state methods. The complex crystallizes with a distorted square-planar geometry about the Rh(I) atom (m symmetry). A weak inter-molecular C-H⋯O… (More)
In the title complex, [Cu(NO(3))(C(18)H(12)F(3)P)(3)], the ligating atoms define a distorted tetrahedon with the three tris-(4-fluoro-phen-yl)phosphane ligands in the basal positions and the nitrate ligand in the axial position. The intra-molecular π-π inter-action [centroid-centroid distance = 3.6113 (11) Å] between two of the 4-fluoro-phenyl groups is… (More)
A range of single-crystal structures of the type [Pd(cod)(LL'-Bid)]A, where LL'-Bid = acetylacetonato (acac), thenoyltrifluoroactetonato (thtfac) and hexafluoroacetylacetonato (hfacac), and A = tetrafluoroborate (BF(4)(-)) and hexafluorophosphate (PF(6)(-)), are reported. The complexes [Pd(cod)(acac)]PF(6) (I), [Pd(cod)(thtfac)]PF(6) (III),… (More)
The title compound, C11H11NO5, is essentially planar, with an r.m.s. deviation of 0.06 Å. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond. In the crystal, molecules are linked by two pairs of C-H⋯O hydrogen bonds, forming sheets, lying parallel to (101), which enclose R 4 (4)(26) ring motifs.
The Cu(I) atom in the title compund, [Cu(C(7)H(2)Br(3)O(2))(C(19)H(17)P)(2)], is located on a twofold rotation axis; the 3,5,7-tribromo-tropolonate anion coordinates as a bidentate ligand with a bite angle of 76.42 (9)°. An intra-molecular C-H⋯O inter-action occurs. Within the crystal, extensive weak C-H⋯π inter-actions contribute to the herringbone pattern… (More)
THE TITLE COMPOUND [SYSTEMATIC NAME: (E)-2-hy-droxy-5-(phenyl-diazen-yl)cyclo-hepta-2,4,6-trien-1-one], C(13)H(10)N(2)O(2), is essentially planar with an r.m.s. deviation of 0.036 (2) Å and a dihedral angle of 1.57 (8)° between the phenyl and tropolone rings. In the crystal, mol-ecules are linked by pairs of O-H⋯O hydrogen bonds into inversion dimers. The… (More)
In the title compound, C(15)H(15)N(5)O(4), a nitro-formazan derivative, the formazan unit is essentially planar with an r.m.s. deviation of 0.0204 (6) Å and adopts a closed syn,s-cis configuration with an intra-molecular N-H⋯N hydrogen bond. The formazan plane makes dihedral angles of 4.32 (5) and 24.35 (5)° with the benzene rings. The dihedral angle… (More)
The title compound, C(29)H(26)O(4), is essentially planar in the acetophenone portion that includes both the hy-droxy and a benz-yloxy O atoms, with an r.m.s. deviation of 0.0311 Å. The other two substituents inter-sect the plane at 70.45 (3) and 59.55 (4)°. In the molecule there is an intramolecular O-H⋯O hydrogen bond. In the crystal, mol-ecules are… (More)
In the title compound, [Rh(C(22)H(32)N(3)O(5))(CO)(2)], the Rh(I) atom is coordinated by two carbonyl ligands and two tropolonate O atoms in a distorted square-planar geometry. It is an example of a new type of tropolone derivative that has not been characterized via solid-state methods. Weak intra-molecular C-H⋯N and inter-molecular C-H⋯O hydrogen bonds,… (More)
