4,4-Bis(1H-pyrrol-2-yl)penta-nol.

ABSTRACT: The title achiral compound, C(13)H(18)N(2)O, crystallized in the chiral monoclinic space group P2(1). The pyrrole rings are inclined to one another by 62.30?(11)°, and the propanol chain is in an extended conformation. In the crystal, the two pyrrole NH groups are involved in inter-molecular N-H?O hydrogen bonds, leading to the formation of a helical arrangement propagating along the b axis. An inter-esting feature of the crystal structure is the absence of any conventional hydrogen bonds involving the hydr-oxy H atom. There is, however, a weak inter-molecular O-H?? inter-action involving one of the pyrrole rings.

1,5-Bis(2,5-dimethyl-1H-pyrrol-1-yl)naphthalene.

Project description:In the title compound, C(22)H(22)N(2), the asymmetric unit contains one half-mol-ecule. A crystallographic inversion centre is located at the mid-point of the bond common to both rings, in the central naphthalene unit. Quantum-mechanical ab initio calculations on the isolated mol-ecule showed that the minimum energy configuration occurs when the naphthalene ring system and the pyrrolyl groups deviate only slightly from perpendicularity. In the crystal, due to the effects of crystal packing, the mol-ecule deviates by approximately 4° from the a priori expected ideal value of 90° [C-C-N-C torsion angle = 86.11?(15)°].

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)°.

1,1'-(4-Oxoheptane-1,7-di-yl)bis-(2-methyl-1H-benzimidazole) penta-hydrate.

Project description:The title compound, C(23)H(26)N(4)O·5H(2)O, has noncrystallographic twofold rotation symmetry in the solid state. It crystallizes with five solvent water mol-ecules in the asymmetric unit. Four of these water mol-ecules are connected with each other via hydrogen-bonding inter-actions to form two types of centrosymmetric hexa-meric (H(2)O)(6) rings. Via edge sharing of the hexa-mers, the water clusters thus build infinite chains that stretch parallel to the a axis. The fifth water mol-ecule provides an additional connection between the two hexa-meric (H(2)O)(6) units via hydrogen bonds to both rings. The water mol-ecules in the channels along the a axis are also bonded via O-H?N hydrogen bonds to the organic units, and face-to-face ?-? inter-actions [with centroid-to-centroid distances of 3.656?(1)?Å and average face-to-face distances of 3.431?(5)?Å] between the aromatic rings of adjacent mol-ecules complete the inter-molecular inter-actions in this structure.

Project description:The dinuclear title complex, [Ti(2)(C(10)H(15))(2)(C(7)H(2)F(5)O)(4)O], features two Ti(IV) atoms bridged by an O atom. Each Ti atom is bonded to a ?(5)-penta-methyl-cyclo-penta-dienyl ring, two (penta-fluoro-phen-yl)methano-late anions and to the bridging O atom. The environment around each Ti atom can be considered as a distorted tetra-hedron.

Bis(1-tosyl-2-pyrrol-yl)ethyne.

Project description:The title mol-ecule, C(24)H(20)N(2)O(4)S(2), has crystallographic inversion symmetry with a triple-bond distance of 1.206?(2)?Å. The alkyne is not quite linear, with a C-C C angle of 175.78?(16)°. The planar pyrrole rings are parallel but offset from coplanarity by 0.318?(1)?Å. The conformation of the sulfonyl group with respect to the pyrrole ring is such that an O atom is nearly eclipsed with this ring, having an O-S-N-C torsion angle of 3.48?(11)°. C-H?O inter-actions [C?O 3.278?(2)?Å, 136° about H] between pyrrole H and sulfonyl O atoms lead to the formation of ladder-like chains.

Bis[2,3,4-trimethyl-5-[(3,4,5-trimethyl-2H-pyrrol-2-yl-idene-?N)meth-yl]-1H-pyrrolato-?N]copper(II).

Project description:In the title complex, [Cu(C(15)H(19)N(2))(2)] or [Cu(L(2))] (HL is 3,3',4,4',5,5'-hexa-methyl-pyrromethene), the Cu(II) atom is coordinated by four N atoms [Cu-N 1.939?(2)-1.976?(2)?Å] from two L ligands in a distorted tetra-hedral geometry. The mean planes of the CuN(2)C(3) metallocyclic rings form a dihedral angle of 72.73?(6)°. In the L ligands, the pyrrole rings are inclined to each other at dihedral angles of 3.03?(7) and 9.83?(7)°. The crystal packing exhibits weak inter-molecular C-H?? inter-actions, which form chains in [100].

2-[4-(4,5-Dihydro-1H-pyrrol-2-yl)phen-yl]-4,5-dihydro-1H-imidazole.

Project description:The mol-ecule of the title compound, C(12)H(14)N(4), lies about a crystallographic inversion centre. The five- and six-membered rings are twisted from each other, forming a dihedral angle of 18.06?(7)°. In the crystal structure, neighbouring mol-ecules are linked by inter-molecular N-H?N hydrogen bonds into one-dimensional infinite chains forming 18-membered rings with R(2) (2)(18) motifs. The crystal structure is further stabilized by weak inter-molecular ?-? stacking [centroid-centroid distance = 3.8254?(6)?Å] and C-H?? inter-actions.
