(E)-1-Phenyl-3-[4-(trifluoro-meth-yl)phen-yl]prop-2-en-1-one.

In the title compound, C(16)H(11)F(3)O, the dihedral angle between the two rings is 48.8 (2)°. The crystal packing exhibits no classical inter-molecular inter-actions between the mol-ecules.

Di-µ-aqua-bis-{diaqua-[µ-4-({4-[bis-(2-hy-droxy-eth-yl)amino]-6-chloro-1,3,5-triazin-2-yl}amino)-benzene-sulfonato]-sodium(I)}.

In the dinuclear title compound, [Na(2)(C(13)H(15)ClN(5)O(5)S)(2)(H(2)O)(6)](n), two Na(+) cations, disposed about a centre of inversion, are linked by two bridging water mol-ecules. The coordination geometry is based on an O(5) donor set defined by four water mol-ecules and a 4-amino-benzene-sulfonate O atom in a distorted trigonal-bipyramidal geometry. In the crystal, significant O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds lead to the formation of a three-dimensional architecture.

3-Nitro-2-phenyl-chroman.

In the title compound, C(15)H(13)NO(3), the dihedral angle between the two aromatic rings is 79.25 (16)°.

Diphenyl-methyl isothio-cyanate.

The asymmetric unit of the title compound, C(14)H(11)NS, contains two mol-ecules in which the dihedral angles between the phenyl rings are 77.23 (7) and 86.30 (7)°. No aromatic π-π stacking inter-actions are observed.

1-Bromo-2-[(E)-2-nitro-ethen-yl]benzene.

In the title compound, C(8)H(6)BrNO(2), the dihedral angle between the planes of the benzene ring and the nitro group is 22.99 (12)°. In the crystal, inversion dimers associated by pairs of short Br⋯O contacts [3.2319 (17) Å] occur.

Diphenyl chloro-thio-phospho-nate.

The complete mol-ecule of the title compound, C(12)H(10)ClO(2)PS, is generated by crystallographic mirror symmetry, with the P, S and Cl atoms lying on the mirror plane. The resulting PO(2)SCl tetra-hedron is significantly distorted [O-P-O = 96.79 (9)°]. The crystal packing exhibits no directional inter-actions.
