Di-μ-bromido-bis­{[N,N-dimethyl-N′-(thio­phen-2-yl­methyl­idene)ethane-1,2-diamine]­copper(I)]}

In the crystal structure of the title compound, [Cu₂Br₂(C₉H₁₄N₂S)₂], the mol­ecule resides about a crystallographic inversion center. The coordination sphere around each copper ion has a distorted tetra­hedral geometry, with ligation by two bridging bromide ions, an amine N atom and an imine N atom. The thio­phene ring is disordered over two sites, with occupancies of 0.719 (3) and 0.281 (3). Weak C—H...π inter­actions feature in the crystal packing.

5-(Thio­phen-2-ylmeth­yl)-1,3,4-thia­diazol-2-amine

In the title mol­ecule, C₇H₇N₃S₂, the dihedral angle between the thio­phene and thia­diazole rings is 72.99 (5)°; the two rings are oriented so that the S atoms in each ring are on the same side. In the crystal, the three-dimensional network involves strong N—H...O hydrogen bonds, as well as C—H...π and π–π stacking inter­actions [centroid–centroid distances = 3.654 (1) and 3.495 (1) Å].

Trimethyl­ammonium dichlorido­triphenyl­stannate(IV)

In the structure of the title monomeric coordination salt, (C₃H₁₀N)[Sn(C₆H₅)₃Cl₂], the Sn^IV atom is five coordinate, with the SnC₃Cl₂ entity in a trans trigonal–bipyramidal arrangement and the chlorine atoms in apical positions. In the crystal, the cations and anions are connected by N—H...Cl hydrogen bonds.

N,N-Dicyclo­hexyl­cyclo­hexa­ne­carboxamide

In the title compound, C₁₉H₃₃NO, all three cyclo­hexane rings adopt chair conformations. The crystal packing features weak C—H...O inter­actions, forming a supra­molecular chain along the c axis.

1-{4-[Bis(4-fluoro­phen­yl)meth­yl]piperazin-1-yl}ethanone

In the title compound, C₁₉H₂₀F₂N₂O, the six-membered piperazine group adopts a slightly distorted chair conformation. The dihedral angle between the mean planes of the two benzene rings is 73.4 (6)°. The mean plane of the ethanone group is twisted from the mean planes of the two benzene rings by 66.7 (8) and 86.2 (6)°. In the crystal, C—H...O and C—H...F inter­actions link the molecules, forming a three-dimensional structure.

[2-(Biphenyl-4-yl)-1,3-thia­zol-4-yl]methanol

In the title compound, C₁₆H₁₃NOS, the central benzene ring makes dihedral angles of 3.25 (7) and 41.32 (8)°, respectively, with the thia­zole and phenyl rings. In the crystal, O—H...N hydrogen bonds link the mol­ecules into a chain along the c axis. A weak C—H...O inter­action further connects the chains into a layer parallel to the ac plane.

N,N′-Dibenzyl-N′′-(2-chloro-2,2-difluoro­acet­yl)phospho­ric triamide

In the title mol­ecule, C₁₆H₁₇ClF₂N₃O₂P, the N—H unit of the C(=O)NHP(=O) fragment adopts a syn orientation with respect to the P=O group. The two F atoms and the Cl atom of the ClF₂C group are disordered over two sets of sites with refined occupancies of 0.605 (6) and 0.395 (6). In the crystal, mol­ecules are linked via N—H...O=C hydrogen bonds and the (N—H...)(N—H...)O=P group into chains along [010].

(E)-N′-(4-Meth­oxy­benzyl­idene)-2-m-tolyl­acetohydrazide

In the title mol­ecule, C₁₇H₁₈N₂O₂, the benzene rings form a dihedral angle of 83.0 (7)°. In the crystal, N—H...O hydrogen bonds, in an R²₂(8) graph-set motif, link mol­ecules into centrocymmetric dimers, and weak C—H...π inter­actions further link these dimers into columns in [100].

2-(2-Nitro­phen­yl)acetohydrazide

In the title compound, C₈H₉N₃O₃, the dihedral angle between the benzene ring and the acetohydrazide C—C(=O)—N—N plane [maximum deviation = 0.0471 (13) Å] is 87.62 (8)°. The nitro group is twisted by 19.3 (2)° with respect to the benzene ring. In the crystal, N—H...O hydrogen bonds link the mol­ecules into a double-column structure along the b axis.
