Insight into the crystallization process: relationships between crystal structures and properties of copper(ii) coordination polymers containing dimethylbis(4-pyridyl)silane

Construction of helical coordination polymers via flexible conformers of bis(3-pyridyl)cyclotetramethylenesilane: metal(ii) and halogen effects on luminescence, thermolysis and catalysis

“…Such kinds of bis(3-pyridyl) ligands were confirmed to have stable conformers for helical coordination polymers. 13,14 Selfassembly of MX 2 with L smoothly afforded, in high yields, coordination polymeric species of [MX 2 L] composition, which are colorless single crystals without any solvate molecules, as suitable for X-ray crystallographic measurements. All of the reactions were initially run in the 1 : 1 mole ratio of M(II) : L; the crystalline products were not significantly affected by changes of either the mole ratio or the concentration, thus indicating that the coordination polymeric helical species is thermodynamically stable.…”

“…[10][11][12] In particular, tuning of M-/P-helicity and helical pitch is the most intriguing topic in the field of helical-molecular chemistry. [13][14][15][16][17] Indeed, aesthetic tunable helical architectures have been synthesized via an optimal coordination of appropriate ligands and metal ions. [18][19][20][21] Various dialkylbis-(4-pyridyl)silanes constructed via stable skewed conformers between two N-donors have been known to be useful helical tectonics.…”

“…[18][19][20][21] Various dialkylbis-(4-pyridyl)silanes constructed via stable skewed conformers between two N-donors have been known to be useful helical tectonics. 13,14 However, the construction and behavior of helical coordination polymers containing a relatively rigid cyclic-silane as a helical tectonic have remained unexplored. In this context, one crucial aim of the present study was to explore the construction and behavior of helices containing a rigid 5-membered cyclic-silane.…”

Polyrotaxaned versus Interdigitated Super‐Arrays of Loop‐and‐Chain Strands: Role of the Anion in Formation of Silver(0) Particles

“…[1][2][3][4][5][6][7][8][9][10][11][12] The self-assembly of taskspecific coordination networks can be obstructed by various unpredictable weak interactions and subtle reaction factors. Additional uncertainties in these crystal engineering systems exist in the super-array of basic units; that is, catenanes, rotaxanes, molecular knots, interdigitation, simple packing, and others.…”

Triple-meso helices as alcohol reservoirs and discriminators: structural properties and thermal behaviors of silver(i) coordination molecular braids containing diethylbis(4-pyridyl)silanes

“…Designed helical coordination polymers' construction and functionalization have become hot issues in the field of multidisciplinary supramolecular science over the past two decades, owing to their practical applications in asymmetric catalysis, chiral separation, nonlinear optics, template precursors, memory devices, biomimetics, DNA, structural biology, specific ion recognition, and molecular-level reaction vessels. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] The recent construction of a new type of helical motif, then, has been met with great interest. [17][18][19] Unfamiliar frames with novel entanglements, such as multiple helices, Borromean architectures, and polyrotaxanes, [20][21][22][23][24] ubiquitous in nature, contribute to intriguing self-assembly chemistry.…”
