9-(1,1-Dimethyl-3-oxobut-yl)adenine.

ABSTRACT: The title compound, C(11)H(15)N(5)O, crystallizes with two independent mol-ecules in the asymmetric unit, both of which contain essentially planar imidazole and pyrimidine rings [maximum deviations = 0.002?(2) and 0.026?(2)?Å, respectively, for the first mol-ecule, and 0.001?(2) and 0.025?(2)?Å for the second]; the dihedral angles between the rings are 2.1?(2) and 1.7?(2)° in the two mol-ecules. The crystal structure is stabilized by inter-molecular N-H?N hydrogen bonds, defining chains along a, which are further linked by weak inter-molecular ?-? contacts [centroid centroid distance = 3.7989?(16)?Å] into planes parallel to (01).

1,1'-Dimethyl-1,1'-(butane-1,4-di-yl)dipyrrolidinium dibromide methanol disolvate.

Project description:In the title compound, C(14)H(30)N(2) (2+)·2Br(-)·2CH(3)OH, two terminal C atoms of the butane chain are connected to two N atoms of the 1-methyl-pyrollidines, forming a linear diquaternary ammonium cation. The cation lies across a centre of inversion located between the two central C atoms of the butane chain. The asymmetric unit therefore comprises one half-cation, a bromide anion and a methanol solvent mol-ecule. In the crystal structure, the bromide anions are linked to the methanol solvent mol-ecules by O-H⋯Br hydrogen bonds.

1,1'-Bis(tert-butyl-dimethyl-sil-yl)ferrocene.

Project description:The asymmetric unit of the title compound, [Fe(C11H19Si)2], consists of one half of a ferrocene derivative. The Fe(II) atom lies on a twofold rotation axis, giving an eclipsed conformation for the cyclo-penta-dienyl ligands. No significant inter-molecular inter-actions are observed in the crystal structure.

1,1'-(2,5-Dimethyl-thio-phene-3,4-di-yl)diethanone.

Project description:The title compound, C(10)H(12)O(2)S, crystallizes with four mol-ecules in the asymmetric unit. The main conformational difference between these mol-ecules is the orientation of the acetyl groups with respect to the ring. Whereas one acetyl group is only slightly twisted with respect to the thio-phene ring [C-C-C-O torsion angles = 165.7 (4), -164.6 (4), 164.3 (4) and -163.6 (4)°], the other acetyl group is markly twisted out of the ring plane [C-C-C-O torsion angles = -61.2 (6), 61.3 (7), -59.7 (7) and 59.9 (6)°]. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions into infinite chains along the c axis.

1,4-Bis(1,1-dimethyl-prop-yl)-2,5-dimeth-oxy-benzene.

Project description:The title compound, C(18)H(30)O(2), was prepared by Friedel-Crafts alkyl-ation of 1,4-dimeth-oxy-benzene with 2-methyl-2-butanol. The complete mol-ecule is generated by the application of a crystallographic centre of inversion. The two meth-oxy groups are oriented in the same plane of the aromatic ring [C-C-O-C torsion angle = 9.14?(16)°]. While one methyl group of the tert-pentyl substituent is coplanar with the benzene ring [C-C-C-C = 0.45?(15)°] and lies towards the less-hindered H atom, the other methyl and ethyl groups are directed to either side of the benzene ring [C-C-C-C torsion angles = 118.78?(12) and 59.11?(14)°, respectively]. In the crystal, the hydro-phobic mol-ecules pack to form a brick-wall-like architecture.

N-(2-Hy-droxy-1,1-dimethyl-eth-yl)-benzene-sulfonamide.

Project description:In the title mol-ecule, C(10)H(15)NO(3)S, the S atom is bonded in a distorted tetra-hedral geometry. In the crystal structure, inter-molecular N-H?O, O-H?O and weak C-H?O hydrogen bonds connect the mol-ecules to form a two-dimensional network parallel to (100). The 2-methyl-propan-1-ol group is disordered over two orientations with occupancies of 0.570?(3) and 0.430?(3).

(R)-2-[(Dimethyl-amino)-meth-yl]-1,1'-bis-(diphenyl-phosphinothio-yl)ferrocene dichloromethane monsolvate.

Project description:In the title compound, [Fe(C(20)H(21)NPS)(C(17)H(14)PS)]·CH(2)Cl(2), both cyclo-penta-dienyl (Cp) rings constituting the ferrocene unit are substituted by a sulfur-protected diphenyl-phosphine. One of the Cp ligands is additionally substituted by a dimethyl-amino-methyl group causing the chirality of the mol-ecule. Surprisingly, although the synthetic procedure yielded the title compound as a racemic mixture, the reported crystal is enanti-omerically pure with the R absolute configuration. The dimethyl-amino group is exo with respect to the Cp ring. Both diphenyl-thio-phosphine groups are trans with respect to the centroid-Fe-centroid direction. Weak intra-molecular C-H⋯S and C-H⋯π inter-actions between symmetry-related mol-ecules are observed. The contribution of the disordered solvent was removed from the refinement using SQUEEZE in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155].

3,3'-Dimethyl-1,1'-(butane-1,4-di-yl)diimidazolium bis-(tetra-fluoro-borate).

Project description:The title compound, C(12)H(20)N(4) (2+)·2BF(4) (-), was prepared by the anion exchange of a dibromide ionic liquid with sodium tetra-fluoro-borate. The asymmetric unit contains one half of the imidazolium cation, which lies about an inversion centre at the mid-point of the central C-C bond of the linking butyl chain. The two planar imidazole rings (r.m.s. deviation = 0.0013?Å) are strictly parallel and separated by 2.625?(7)?Å [vertical distance between the centroids of two imidazole rings], giving the mol-ecule a stepped appearance. In the crystal structure, inter-molecular C-H?F hydrogen bonds link the cations and anions, generating a three-dimensional network.

The 2-methyl-propan-1-ol group of the mol-ecule is disordered over two positions with an 0.592 (4):0.408 (4) occupancy ratio.
