3,3''-Bis(9-hy-droxy-fluoren-9-yl)-1,1':3',1''-terphen-yl.

ABSTRACT: The asymmetric unit of the title compound, C44H30O2, contains two independent mol-ecules in which the terminal rings of the terphenyl element are inclined at angles of 36.3?(1) and 22.5?(1)° with respect to the central ring and the dihedral angles between the fluorenyl units are 72.3?(1) and 62.8?(1)°. In the crystal, pairs of O-H?O hydrogen bonds link the mol-ecules into inversion dimers. The hy-droxy H atoms not involved in these hydrogen bonds form O-H?? inter-actions in which the central terphenyl rings act as acceptors. Weak C-H?O contacts and ?-? [centroid-centroid distance = 4.088?(2)?Å] stacking inter-actions also occur. Taking into account directed non-covalent bonding between the molecules, the crystal is constructed of supramolecular strands extending along the a-axis direction.

The asymmetric unit of the title compound, C44H30O2, contains two independent mol-ecules in which the terminal rings of the terphenyl element are inclined at angles of 36.3 (1) and 22.5 (1)° with respect to the central ring and the dihedral angles between the fluorenyl units are 72.3 (1) and 62.8 (1)°.

Project description:In the title compound, [Fe(C6H12NO5)2], the Fe(II) ion lies on an inversion center and is coordinated by two N atoms and four O atoms from two tridentate N-[2-hy-droxy-1,1-bis-(hy-droxy-methyl)eth-yl]glycine ligands, forming a slightly distorted octa-hedral coordination environment. In the crystal, O-H?O, O-H?N and weak C-H?O hydrogen bonds link mol-ecules, forming a three-dimensional network.

Crystal structures of 3,3'-bis-(hy-droxy-dimethylsilan-yl)azo-benzene and 4,4'-bis-(hy-droxy-dimethyl-silane)azo-benzene.

Project description:The title compounds {systematic names (E)-[diazene-1,2-diylbis(3,1-phenyl-ene)]bis-(di-methyl-silanol) and (E)-[diazene-1,2-diylbis(4,1-phenyl-ene)]bis-(di-methyl-silanol)}, both of the sum formula C16H22N2O2Si2, were obtained by transmetallation of the respective bis-stannylated azo-benzenes with di-chloro-dimethyl-silane and esterification followed by hydrolysis. The asymmetric unit of 3,3'-diazenediylbis[dimeth-yl(phen-yl)silanol] (with the silanol functional group in a meta position) consists of two mol-ecules, of which one occupies a general position, whereas the second is located on a centre of inversion. In 4,4'-diazenediylbis[dimeth-yl(phen-yl)silanol] (with the silanol functional group in a para position) likewise two mol-ecules are present in the asymmetric unit, but in this case both occupy general positions. Differences between all mol-ecules can be found in the torsions about the N=N bond, as well as in the dihedral angles between the benzene rings. In both structures, inter-molecular O-H⋯O hydrogen bonding is observed, leading to the formation of layers parallel to (01-1) for (I) and to chains parallel to the a axis for (II).

Project description:In the title compound, C(27)H(26)O(4), each of the cyclo-hexenone rings adopts a half-chair conformation. The dihedral angle between the two phenyl rings is 89.53 (5)°. The hy-droxy and carbonyl O atoms face each other and are orientated to allow the formation of two intra-molecular O-H⋯O hydrogen bonds, which are typical of xanthene derivatives.

Project description:In the title compound, a new macrocyclic metal complex, [Ag(NO(3))(C(21)H(15)N(3)O(4))], all non-H atoms are in a close-to-planar geometry (except for the nitrate anion), with a maximum out-of-plane deviation of 0.327 (6) Å for a pyridine C atom. The dihedral angle between the least-squares plane through the [3,3'-dihy-droxy-3,3'-bis-(pyridin-3-yl)-1,1'-(pyridine-2,6-di-yl)dipropan-1-one]silver(I) fragment and the nitrate anion is 31.29 (13)°. The mol-ecular structure is stabilized by several inter- and intra-molecular O-H⋯O and C-H⋯O hydrogen bonds. The Ag(I) atom is coordinated by two pyridine N atoms and two O atoms of the nitrate anion in a geometry intermediate between tetrahedral and square-planar.

catena-Poly[[dinitratocopper(II)]-?-4,4''-bis-(1H-benzimidazol-1-yl)-1,1':4',1''-terphen-yl].

Project description:In the title one-dimensional coordination polymer, [Cu(NO(3))(2)(C(32)H(22)N(4))](n), the Cu(2+) ion (site symmetry 2) is coordinated by two nitrate O atoms and two N atoms from two 4,4'-bis-(benzoimidazol-1-yl)terphenyl (L) ligands in a distorted cis-CuN(2)O(2) square-planar coordination geometry. An alternative description of the metal coordination geometry, if long Cu-O contacts to the bonded nitrate anions are considered, is an extremely distorted cis-CuN(2)O(4) octa-hedron. The complete L ligand is generated by crystallographic twofold symmetry and connects the metal ions into infinite chains propagating in [10[Formula: see text]]. The dihedral angle between the benzimidazole ring system and the adjacent benzene (B) ring is 51.12?(11)° and the dihedral angle between the B ring and the central ring is 19.45?(13)°.

The complete ligand is generated by crystallographic twofold symmetry, resulting in an infinite one-dimensional architecture along [101].
