The crystal structure of the title compound features C=O⋯π inter­actions along with C—H⋯O hydrogen bonds.

The Cu^II ions in this compound form a square-pyramidal coordination environment and are bridged by the Cl₄bdc²⁻ and pyz ligands to form a two-dimensional (two-dimensional) layer. The two-dimensional layers are alternately stacked by hydrogen-bonding and C—Cl⋯π inter­actions to form a three-dimensional network.

In the title compound, the Co^II cations are octa­hedrally coordinated by two N-bonded thio­cyanate anions, two 4-methyl­pyridine ligands and two water mol­ecules into discrete complexes that are linked by O—H⋯S hydrogen bonds into layers. Upon heating, the title compound loses the water mol­ecules and transforms into Co(NCS)₂(C₆H₇N)₂, which is already reported in the literature

The mol­ecular structure and crystal packing of 5,5-diphenyl-3-(2-propyn-1-yl)imidazolidine-2,4-dione were studied using single-crystal X-ray diffraction and Hirshfeld surface analysis..

In the crystal of the title compound, N—H⋯O hydrogen bonds lead to the formation of dimers with an inter­action energy of −70.5 kJ mol⁻¹. The two-dimensional fingerprint plots indicate that the major contributions to the crystal packing are from H⋯H (67.9%), C⋯H (13.7%), O⋯H (7.3%) and S⋯H (4.3%) inter­actions.

In the title compound, the aromatic rings are oriented at a dihedral angle of 83.30 (8)°. An intra­molecular C—H⋯O contact generates a five-membered S(5) ring motif. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules through R¹₂(6), R²₂(10), R²₂(14) hydrogen-bond motifs.

The mol­ecular and crystal structures of ketorolac tromethamine are reported. In the crystal, mol­ecules are connected by N—H⋯O and O—H⋯O hy­dro­gen bonds, forming a two-dimensional layer in the (100) plane.

Liquid-assisted grinding (LAG) and microwave synthesis are proposed as alternative routes for the synthesis of cryptands, with reaction times of up to 16 times faster than traditional methods.

We have isolated and structurally chracterized 2,2-di­chloro-3,3-dieth­oxy-1-(4-fluoro­phen­yl)propan-1-ol by simple hy­dro­genation of 2,2-di­chloro-3,3-dieth­oxy-1-(4-fluoro­phen­yl)propan-1-one. Hirshfeld surface analysis was performed.
