X-ray and NMR Crystallography Studies of Novel Theophylline Cocrystals Prepared by Liquid Assisted Grinding
Two new cocrystals of theophylline were prepared by liquid assisted grinding. While compound 1 (theophylline:4-aminosalicylic acid 2:1) was characterized by single crystal X-ray diffraction, theExpand
Thermal transformation of a layered multifunctional network into a metal-organic framework based on a polymeric organic linker.
Thermogravimetry in conjunction with thermodiffractometry showed that the material undergoes a microcrystal-to-microcrystal phase transformation above 300 °C, and Catalyst recycling and leaching tests performed for [La(H(3)nmp)] confirm the heterogeneous nature of the catalytic reaction. Expand
CH3-Tagged Bis(pyrazolato)-Based Coordination Polymers and Metal–Organic Frameworks: An Experimental and Theoretical Insight
The novel coordination polymers M(Me2BPZ) (M = Co, Zn; H2Me2BPZ = 3,3′-dimethyl-1H,1′H-4,4′-bipyrazole), M(H2Me2BPZ)(CH3COO)2(H2O)2 (M = Co, Ni), and Cu(H2Me2BPZ)(Cl)2 were isolated alongExpand
The asymmetric unit of the title compound, C36H24N6, comprises a whole molecule that is tilted with respect to the two pyridine substituents, subtending angles of 36.17 (11) and 34.95  (11)°. Expand
catena-Poly[[triaquachlorido-μ3-malonato-cerium(III)] hemihydrate]
The asymmetric unit of the title compound contains a Ce3+ atom coordinated by a chloride anion, three water molecules and a malonate ligand, and one water molecule of crystallization with a factor of occupancy of 50%. Expand
5-Amino-1H-1,2,4-triazol-4-ium-3-carboxylate hemihydrate
The asymmetric unit of the title compound, C3H4N4O2·0.5H2O, comprises two whole molecules of 5-amino-1H-1,2,4-triazole-3-carboxylic acid in its zwitterionic form, plus one water molecule of crystallization. Expand
Reviewing the Manifold Aspects of Ganciclovir Crystal Forms
Ganciclovir, an active pharmaceutical ingredient against cytomegalovirus, is known to crystallize in the form of anhydrous or hydrated phases. The crystal and molecular structures of two hydratedExpand
The Hg(3,3′-dimethyl-1H,1H′-4,4′-bipyrazolate) coordination polymer: Synthesis, crystal structure and thermal behavior
Abstract The novel coordination polymer Hg(Me2BPZ) (H2Me2BPZ = 3,3′-dimethyl-1H,1′H-4,4′-bipyrazole) was prepared by reacting the H2Me2BPZ ligand and mercury(II) acetate. The crystal structure ofExpand
Highly Luminescent Tris(β-diketonate)europium(III) Complexes Immobilized in a Functionalized Mesoporous Silica
The mesoporous silica MCM-41 functionalized with a chelating pyrazolylpyridine ligand (MCM-41-L2) was used as a support for the immobilization of tris(β-diketonate) complexes Ln(NTA)3 [Ln = Eu, Gd;Expand
Chloramphenicol·cyclodextrin inclusion compounds: co-dissolution and mechanochemical preparations and antibacterial action
β-Cyclodextrin (βCD) inclusion compounds of chloramphenicol in the solid-state were prepared via two different procedures, co-crystallisation from aqueous solution and the solvent-free method ofExpand
