2-(4-Fluoro-phen-yl)-5-iodo-3-phenyl-sulfinyl-1-benzofuran.

Project description:In the title compound, C(20)H(12)FIO(2)S, the dihedral angles between the mean plane [r.m.s. deviation = 0.014?(1)?Å] of the benzofuran fragment and the pendant 4-fluoro-phenyl and phenyl rings are 8.0?(1) and 86.06?(6)°, respectively. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds. The crystal structure also exhibits weak ?-? inter-actions between the furan and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.547?(2)?Å, inter-planar distance = 3.397?(2)?Å and slippage = 1.021?(2)?Å].

Bis[4-(dimethyl-amino)phen-yl]diazene oxide.

Project description:The asymmetric unit of the title compound, C(16)H(20)N(4)O, contains six independent approximately planar mol-ecules and is best described as a commensurate modulation of a P2(1)/c parent. Two sets of disordered mol-ecules share almost the same locations (related by an in-plane translation), ensuring that the c-glide plane condition is not attained. C-H⋯O inter-actions provide structural cohesion. The site occupancy factors of the disordered molecules are ca 0.72/0.28 and 0.67/0.33.

2-(4-Fluoro-phen-yl)-5-iodo-7-methyl-3-phenyl-sulfinyl-1-benzo-furan.

Project description:In the title compound, C21H14FIO2S, the dihedral angles between the mean plane [r.m.s. deviation = 0.007 (1) Å] of the benzo-furan fragment and the pendant 4-fluoro-phenyl and phenyl rings are 3.66 (7) and 82.37 (6)°, respectively. In the crystal, mol-ecules are linked by pairs of C-H⋯I hydrogen bonds into centrosymmetric dimers, which are further packed into stacks along the b axis by C-H⋯O hydrogen bonds. In addition, the stacked mol-ecules exhibit inversion-related S⋯O contacts [2.9627 (14) Å] involving the sulfinyl groups.

Project description:The crystal structures and Hirshfeld surface analyses of four similar azo compounds are reported. (E)-1-[1-(4-tert-Butyl-phen-yl)-2,2-di-chloro-ethen-yl]-2-phenyl-diazene, C18H18Cl2N2, (I), and (E)-1-[1-(4-tert-butyl-phen-yl)-2,2-di-chloro-ethen-yl]-2-(4-methyl-phen-yl)diazene, C19H20Cl2N2, (II), crystallize in the monoclinic space group C2/c with Z = 8, and (E)-1-[1-(4-tert-butyl-phen-yl)-2,2-di-chloro-ethen-yl]-2-(4-meth-oxy-phen-yl)diazene, C19H20Cl2N2O, (III), in the monoclinic space group P21/c with Z = 4. (E)-1-[1-(4-tert-Butyl-phen-yl)-2,2-di-chloro-ethen-yl]-2-(3-methyl-phen-yl)diazene, C19H20Cl2N2, (IV), crystallizes in the triclinic space group P with Z = 4 and comprises two mol-ecules (A and B) in the asymmetric unit. In the crystal structures of (I) and (II), mol-ecules are linked by C-H⋯π and C-Cl⋯π inter-actions, forming layers parallel to (02), while mol-ecules of (III) are linked by C-H⋯O contacts, C-H⋯π and C-Cl⋯π inter-actions forming layers parallel to (02). The stability of the mol-ecular packing is ensured by van der Waals forces between these layers. In the crystal structure of (IV), mol-ecules are linked by C-H⋯π and C-Cl⋯π inter-actions, forming a tri-periodic network.

Project description:In the title compound, C(15)H(15)N(5)O(2)S(2), the phenyl rings make dihedral angles of 4.03?(4) and 9.77?(5)° with the plane defined by the central N-N-C-N-N atoms (r.m.s. deviation = 0.010?Å).

The shortest centroid-centroid distance of 3.707?Å occurs between the two ?-systems N-N-C-N-N and the benzene ring in the diazene 1-position. The H atom bound to the N atom is involved in intra-molecular N-H?N and N-H?S contacts, while the nitro O atoms are involved in inter-molecular C-H?O contacts.

2-[(2,6-Diisopropyl-phen-yl)imino-meth-yl]-4-iodo-phenol.

Project description:The asymmetric unit of title compound, C(19)H(22)INO, contains two independent mol-ecules. Classical intra-molecular O-H?N hydrogen bonds stabilize the mol-ecular structures.

In both mol-ecules, the aromatic rings are nearly perpendicular to each other [dihedral angles = 84.26?(17) and 86.69?(15)°].
