ТЕРМИЧЕСКОЕ РАЗЛОЖЕНИЕ КАТИОННЫХ, АНИОННЫХ И ДВОЙНЫХ КОМПЛЕКСНЫХ СОЕДИНЕНИЙ 3d-МЕТАЛЛОВ

“…Кроме того, в большинстве случаев эти соединения содержат несколько молей кристаллизационной воды на моль комплекса. Из числа нейтральных лигандов наиболее часто употребляются аммиак [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] и органические диамины [31][32][33][34][35][36][37][38][39][40][41][42][43], образующие наиболее прочные и инертные соединения с переходными металлами d 5 -d 10 . Широкие исследования термической устойчивости комплексов преимущественно гексаминового типа проведены Вендландтом с сотрудниками [16,17,20,29,40,43].…”

“…При этом надо отметить, что в работах [20,[22][23][24] удаление аммиака наблюдается уже значительно ниже 100 °С. Кроме того, разложение аммиачных катионных комплексов происходит ступенчато: так, согласно [22] [32].…”

Synthesis, Structural Characterization, and Water Vapor Sorption Behavior of Two Ligand Ratio-Dependent Supramolecular Networks, [Cd(2,2′-bpym)1.5(BDC)]·0.5(2,2′-bpym)·5H2O and [Cd(2,2′-bpym)0.5(BDC)(H2O)3]

“…Three-dimensional (3D) supramolecular networks built up via the self-assembly of metal complexes, coordination polymers (CPs), or metal–organic frameworks (MOFs) , are an important research issue, not only in their structural diversity of supramolecular networks assembled via various types of intermolecular forces − but also in their potentially diverse functional applications. − Bridging ligands have been widely used in the developments of CPs or MOFs and are now at the heart of supramolecular coordination chemistry . Rigid multi-carboxylate ligands have been extensively employed to link metal ions and produce high-dimensional frameworks. − For example, 1,4-benzenedicarboxylate (BDC 2– ) is the key bridging ligand with various kinds of coordination modes in the construction of archetypical MOFs. , In addition, conjugated N -containing heterocycles are important bridging ligands.…”

Sponge-Like Water De-/Ad-Sorption versus Solid-State Structural Transformation and Colour-Changing Behavior of an Entangled 3D Composite Supramolecuar Architecture, [Ni4(dpe)4(btc)2(Hbtc)(H2O)9]·3H2O

“…The study of 3D supramolecular architectures assembled via coordination polymers (CPs) [1] or metal organic frameworks (MOFs) [1,2] with various types of structural topologies is an important research topic, not only in terms of their structural diversity in the solid-state structural studies of supramolecular chemistry [3,4,5,6,7,8,9,10,11,12], but also for their potential functional applications. A variety of supramolecular architectures have been obtained on the concepts of crystal engineering assembled by a large range of bonding forces, ranging from the classic M–L covalent bonds, to strong halogen interactions [13,14,15,16,17,18,19,20,21] or hydrogen bonds [22], to much weaker forces, such as weak hydrogen bonds [23,24] and π–π stacking interactions of small aromatics [25,26,27,28]. In the field of supramolecular chemistry, entangled 3D supramolecular networks serve as an important subject via the assembly of various CPs, as seen in interpenetration, polycatenane, interdigitation, polythread, and other species [29,30,31,32,33,34,35,36].…”
