Bis(furan-2-ylcarbon-yl) diselenide.

ABSTRACT: The title mol-ecule, C(10)H(6)O(4)Se(2), lies on a twofold rotation axis. The Se-Se bond length of 2.305?(3)?Å is similar to that in diphenyl diselenide [2.3066?(7) and 2.3073?(10)?Å for the P and M isomers, respectively] and longer than that in 1,8-diseleno-naph-thalene [2.0879?(8)?Å]. The mol-ecule adopts a gauche conformation with respect to the C=O groups.

The title mol-ecule, C(10)H(6)O(4)Se(2), lies on a twofold rotation axis. The Se-Se bond length of 2.305 (3) Å is similar to that in diphenyl diselenide [2.3066 (7) and 2.3073 (10) Å for the P and M isomers, respectively] and longer than that in 1,8-diseleno-naph-thalene [2.0879 (8) Å].

Bis[5-(4-methoxy-benz-yl)furan-3-yl]methanone.

Project description:The title compound, C(25)H(22)O(5), was obtained by a dehydrogenative carbonyl-ation reaction. It crystallizes with one half-mol-ecule in the asymmetric unit. The mol-ecules have crystallographic C(2) symmetry and the two atoms of the carbonyl group are located on the rotation axis. The meth-oxy groups are coplanar with the benzene ring to which they are attached [C-C-O-C = 1.0?(6)°]. The two furan rings are inclined at 17.3?(3)° with respect to each other and the dihedral angle between the furan ring and the benzene ring is 75.83?(12)°. The crystal structure is stabilized by C-H?O hydrogen bonds.

Close intermolecular C-H?Cl and C-H?(furan ring) inter-actions complete the hydrogen bonding.

Bis[N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidato]iron(III) perchlorate monohydrate.

Project description:The structure of the title salt complex, [Fe(C(12)H(8)N(3)O(2))(2)]ClO(4)·H(2)O, contains one Fe(III) cation, two N-(pyridin-2-ylcarbon-yl)pyridine-2-carboxamidate (bpca(-)) anions, one perchlorate anion and one water mol-ecule. The Fe(III) cation has an approximate octa-hedral geometry, defined by six N atoms from two bpca(-) anions. The nearly parallel [dihedral angle = 1.50?(1)°] bpca(-) anions form two-dimensional supermolecules along the a axis by the way of weak ?-? stacking inteactirons [centroid-centroid distances = 3.948?(2), 4.000?(2), 3.948?(2), 3.911?(2), 3.897?(2), 3.984?(2) and 3.929?(2)?Å]. Intra- and inter-molecular C-H?O hydrogen bonding occurs. The water mol-ecule [occupancies 0.520?(5) and 0.480?(5)], two carbonyl O atoms [occupancies 0.622?(7) and 0.378?(7)] and the four perchlorate O atoms [occupancies 0.887?(4) and 0.113?(4)] are each disordered over two positions.

Bis(?-2-{bis-[(2-oxidobenzyl-idene)amino]-meth-yl}phenolato)bis-[(tetra-hydro-furan)-samarium(III)] tetra-hydro-furan disolvate.

Project description:In the centrosymmetric binuclear complex of the title solvate, [Sm(2)(C(21)H(15)N(2)O(3))(2)(C(4)H(8)O)(2)]·2C(4)H(8)O, the Sm(III) is coordin-ated in a distorted monocapped octa-hedral geometry by four O atoms and two N atoms from two tridentate deprotonated 2-{bis-[(2-oxidobenzyl-idene)amino]-meth-yl}phenolate ligands and an O atom of a tetra-hydro-furan (THF) mol-ecule. The Sm?Sm distance in the complex is 3.8057?(4)?Å. Parts of the coordinating THF mol-ecule are disordered over two sets of sites in a 0.56?(3):0.44?(3) ratio. The complex and solvent mol-ecules are linked into a three-dimensional structure via C-H?O hydrogen-bonding inter-actions.

4,6-Bis(diphenyl-phosphan-yl)dibenzo[b,d]furan.

Project description:The asymmetric unit of the title compound, C(36)H(26)OP(2), comprises two mol-ecules which have slightly different conformations of the phenyl ring substituents. In both mol-ecules, the dibenzofuran unit is close to being planar, with dihedral angles of 3.20 (3) and 1.86 (2)° for the two mol-ecules. Its planarity affects the intra-molecular distances between P atoms, with P⋯P distances of 5.574 (2) and 5.485 (2) Å for the two mol-ecules.

Bis{2-[(Tri-phenyl-meth-yl)amino]-phen-yl} diselenide aceto-nitrile monosolvate.

Project description:The mol-ecular structure of the title compound, C50H40N2Se2·C2H3N, shows a syn conformation of the benzene rings bound to the Se atoms, with an Se-Se bond length of 2.3529?(6)?Å and a C-Se-Se-C torsion angle of 93.53?(14)°. The two Se-bonded aromatic ring planes make a dihedral angle of 18.42?(16)°. Intra-molecular N-H?Se hydrogen bonds are noted. Inter-molecular C-H?Se inter-actions give rise to supra-molecular chains extended along [100]. One severely disordered aceto-nitrile solvent mol-ecule per asymmetric unit was treated with SQUEEZE in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]; the crystal data take the presence of this mol-ecule into account.

(+)-(S,S)-1,3-Bis[(tetra-hydro-furan-2-yl)-meth-yl]thio-urea.

Project description:The title compound, C(11)H(20)N(2)O(2)S, is an enanti-omerically pure heterocycle-substituted thio-urea synthesized under solvent-free conditions. The thio-urea unit adopts a ZZ conformation, with the HN-(C=S)-NH core almost planar and the tetra-hydro-furfuryl groups placed below and above this plane. The whole mol-ecule thus approximates to noncrystallographic C(2) symmetry. Unexpectedly, the C=S group is not involved in inter-molecular hydrogen bonding, as generally observed in homodisubstituted thioureas. Instead, mol-ecules form a one-dimensional network based on weak N-H?O(heterocycle) hydrogen bonding, resulting in a zigzag ribbon-like structure around the crystallographic 2(1) screw axis along [100].

2,3-Bis(furan-2-yl)pyrazino-[2,3-f][1,10]phenanthroline.

Project description:The mol-ecule of the title compound, C22H12N4O2, is located on a twofold rotation axis. The dihedral angle between the furan and pyrazine rings is 34.8?(7)°, and that between the furan rings is 46.92?(7)°. A ?-? stacking interaction occurs between adjacent pyrazino[2,3-f][1,10]phenanthroline units, with an interplanar distance of 3.5862?(12)?Å.

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

Project description: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.
