Dehydration of the hybrid compound [Ni3(OH)2(tp)2(H2O)4] (1) upon heating led to sequential removal coordinated water molecules give [Ni3(OH)2(tp)2(H2O)2] (2) at T1 = 433 K and thereafter anhydrous [Ni2(OH)2(tp)] (3) T2 483 K. These two successive structural transformations were thoroughly characterized by powder X-ray diffraction assisted density functional theory calculations. The crystal structures new compounds 2 3 determined. It was shown that (433 K) infinite nickel oxide chains built...
Magnetocaloric effect: A GdIII-based metal–organic framework (MOF) has an unprecedented large magnetocaloric effect around 2 K. It was shown to be interesting magnetorefrigerant for ultralow-temperature applications, because it combines the advantages of molecular materials and robustness a with strong 3D chemical connections (see figure). Detailed facts importance specialist readers are published as "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They...
A single crystal X-ray diffraction study was performed on the compounds [Ca2Al(OH)6]·[Cl∼0.5(CO3)∼0.25·∼2.25H2O] belonging to cementitious AFm family of general formulae [Ca2Al(OH)6]·[X·nH2O], where X is a monovalent anion, or half divalent anion. The so-called chloro-carboaluminate compound crystallizes in rhombohedral space group with: a=5.7400(4) Å, c=46.7402(4) V=1333.7(2) Å3, Dx=2.054 g/cm−3, and Z=6.

Abstract Zinc‐based metal–organic frameworks (MOFs), binary zinc carboxylates ZnC n C n′ with and = CH 3 (CH 2 ) – COO , have been synthesised characterised for anti‐corrosion applications. The crystallographic structures of 10 14 16 were determied from synchrotron powder diffraction data refined by the Rietveld method. Protective coatings on electrogalvanised steel composed 12 developed formulating a particular “carboxylating” bath. coating exhibits better behaviour than pure Zn(C coatings,...

Long alkane dioic acid molecules bridge these together to afford large distances poor media between dense spin chains. thermal dependence χT product provides evidence for uncompensated antiferromagnetic interactions...
Magnetic refrigerants incorporating Gd3+ ions and light organic ligands offer a good balance between isolation of the magnetic centers their density. We synthesized framework material Gd2(C2O4)3(H2O)6⋅0.6H2O by hydrothermal route characterized its structure. The honeycomb lattice interlinked oxalate in (a,c) plane ensures decoupling terms exchange interactions. This is corroborated measurements indicating negligible interactions this material. magnetocaloric effect was evaluated from...
During transport or the storage, galvanized steel products undergo wet storage stain phenomenon, leading to formation of an extensive white rust zinc. The corrosion are mainly zinc layered hydroxides salts which allow several intercalation coprecipitation reactions allowing easy absorption corrosive anions on surface and then In context developing effective, low-cost, environmentally friendly inhibitors, this study is focused action nontoxic sodium heptanoate formula CH3(CH2)5COONa, noted...

Complex architectures are often found among metal–organic framework (MOF) compounds. The mixed-metal approach to this type of material offers an additional degree structural complexity, and potential tunability their properties, which remains largely unexplored. We present in-depth investigation the crystal chemistry MOFs based on succinate linkers (C4H4O4) having general formula (M′1–xM″x)5(OH)2(C4H4O4)4 with M′/M″ = Mn/Co, Fe/Co, Mn/Fe. distribution metallic elements over three...
