N,N'-(Biphenyl-2,2'-di-yl)bis-(furan-2-carboxamide).

ABSTRACT: The title mol-ecule, C(22)H(16)N(2)O(4), is a 2,2'-disubstituted biphenyl whose phenyl-ene rings are rotated by 66.5?(1)° so as to avoid repulsion by the substituents. Only one of the two amide -NH- fragments engages in hydrogen bonding, and this inter-acts with the amido -C(=O)- acceptor of an inversion-related mol-ecule to generate a hydrogen-bonded dimer.

3,3'-{[(Biphenyl-2,2'-di-yl)bis-(methyl-ene)]bis-(-oxy)}bis-[N-(4-chloro-phen-yl)benzamide].

Project description:In the title compound, C40H30Cl2N2O4, the two benzene rings of the biphenyl unit are twisted with respect to each other, making a dihedral angle of 73.07?(4)°. The benzene rings of the benzamide groups form dihedral angles of 77.09?(5) and 55.48?(6)° with the central biphenyl moiety. In the crystal, mol-ecules are linked through N-H?O hydrogen bonds to form a fused R 2 (2)(38) ring motif which forms a supermolecular ribbon network extending along the [100] plane. In the two 4-chloro-phenyl rings, the five C atoms and their attached H atoms are disordered over two sets of sites, with site-occupancy factors of 0.657?(15):0.343?(15) and 0.509?(13):0.491?(13).

Project description:In the title mol-ecule, C(25)H(19)NO(2), the furyl ring is twisted by 46.3?(1)° with respect to the phenyl-ene ring bearing the amido group. In the stilbene unit, the two phenyl-ene rings (i.e. the rings connected through the -CH=CH- fragment) are twisted by 59.2?(1)°; in the biphenyl-ene unit, the two benzene rings are twisted by 35.5?(1)°. In the crystal structure, mol-ecules are linked by an N-H?O(amido) hydrogen bond into a zigzag chain running along the c axis.

N,N'-(2,2'-Dithiodi-o-phenyl-ene)bis-(furan-2-carboxamide).

Project description:The reaction of 2,2'-dithio-bis(benzenamine) with furan-2-carbonyl chloride produced the bis-amide title compound, C(22)H(16)N(2)O(4)S(2), which, in the crystal, formed a helix; the structure consists of two planar furanoylbenzenamines related by an improper rotation of 96.3° about the S-S bond. The N-furanoylbenzenamine units are planar (maximum deviations = 0.316 and 0.132 Å). Each electron-deficient acyl-furan stacks (centroid-centroid separations of the two pairs of π-π stacked aromatic rings are 3.918 and 3.953 Å) with the electron-rich benzenamine of the other N-furan-oyl-benzenamine unit, leading to a spiral structure. The conformation is stabilized by two bifurcated intramolecular N-H⋯(O,S) interactions.

Project description:In the crystal of the title compound, [Cu(2)Cl(4)(C(50)H(32)N(9)O(8)P(3))(2)], the binuclear mol-ecule is located across an inversion center. Each Cu(2+) cation is coordinated by two pyridine N atoms from symmetry-related 4,4;6,6-bis-(biphenyl-2,2'-diyldi-oxy)-2,2-bis-{2-[5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl]phen-oxy}cyclo-triphosphazene (L) ligands, a pair of bridging Cl(-) anions and a terminal Cl(-) anion, forming a distorted CuCl(3)N(2) square-pyramidal geometry. Weak intra-molecular C-H?O and inter-molecular C-H?N inter-actions occur in the crystal.

(Biphenyl-2,2'-di-yl)di-tert-butyl-phos-phonium trifluoro-methane-sulfonate.

Project description:To aid in the elucidation of catalytic reaction mechanism of palladacycles, we found that reaction of trifluoro-methane-sulfonic acid with a phosphapalladacycle resulted in elimination of the palladium and formation of the title phospholium salt, C20H26P(+)·CF3SO3(-). Selected geometrical parameters include P-biphenyl (av.) = 1.801?(3)?Å and P-t-Bu (av.) = 1.858?(3)?Å, and significant distortion of the tetra-hedral P-atom environment with biphen-yl-P-biphenyl = 93.93?(13)° and t-Bu-P-t-Bu = 118.82?(14)°. In the crystal, weak C-H?O inter-actions lead to channels along the c axis that are occupied by CF3SO3(-) anions.
