Вікові особливості залучення населення до оздоровчо-рекреаційної рухової активності в умовах міського парку
Get PDFРівень залучення населення до оздоровчо-
рекреаційної діяльності у міському парку залежить від
зовнішніх та внутрішніх чинників. До зовнішніх чинників
належать умови життя, матеріальне забезпечення, спосіб
життя, режим рухової активності та мікросередовища. До
внутрішніх – мотиви, інтереси, рівень потреб, тип
темпераменту, емоційний стан, бажання, переконання, стан
здоров’я та спрямованість особистості
4f-Block Metal Complexes as Secondary Building Units in Preparing 4d<i>–</i>4f Coordination Polymers: Preparation, Structures, and Luminescent Properties of [Ln<sub>2</sub>L<sub>6</sub>(H<sub>2</sub>O)<sub>4</sub>]·{[Ln<sub>2</sub>L<sub>4</sub>(H<sub>2</sub>O)<sub>6</sub>](NO<sub>3</sub>)<sub>2</sub>} and {[AgLnL<sub>2</sub>(H<sub>2</sub>O)<sub>3</sub>](NO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>} (L = 3-Pyridinepropinoate, Ln = Eu, Tb, Nd)
No full textThree new 4d–4f metal–organic coordination
polymers
were prepared by using 4f-block metal complexes as secondary building
units. Discrete 4f complexes, [Ln<sub>2</sub>L<sub>6</sub>(H<sub>2</sub>O)<sub>4</sub>]·{[Ln<sub>2</sub>L<sub>4</sub>(H<sub>2</sub>O)<sub>8</sub>](NO<sub>3</sub>)<sub>2</sub>} {Ln = Eu (<b>1</b>),
Tb (<b>2</b>), Nd (<b>3</b>)}, were prepared by microwave-heating
a mixture of Ln(NO<sub>3</sub>)<sub>3</sub>·<i>n</i>H<sub>2</sub>O, 3-pyridinepropionic acid (HL), and NaOH in water
for 1 min. Compounds <b>1</b>–<b>3</b> were subsequently
treated with AgNO<sub>3</sub> to form three-dimensional Ag–Ln
coordination polymers, [AgLnL<sub>2</sub>(H<sub>2</sub>O)<sub>3</sub>](NO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub> {Ln = Eu
(<b>4</b>), Tb (<b>5</b>), Nd (<b>6</b>)}. Compounds <b>1</b>–<b>3</b> are isostructural and consist of two
dimers: a neural dimer and an ionic dimer. In these compounds, the
pyridyl N atoms of ligands do not coordinate to the Ln<sup>3+</sup> ions. In isostructural coordination polymers <b>4</b>–<b>6</b>, the pyridyl N atoms are bonded to soft Ag<sup>+</sup> ions,
and carboxylate oxygen atoms are bonded to hard Ln<sup>3+</sup> ions.
Compounds <b>1</b> and <b>4</b> exhibit practically the
same red luminescence in the solid state, and compounds <b>2</b> and <b>5</b> exhibit the green luminescence, but compounds <b>3</b> and <b>6</b> do not exhibit photoluminescence in the
visible region
