хелатные полимеры — coordination polymers

Coordination

The crystal structure and dimensionality of the coordination polymer is determined by the functionality of the linker and the coordination geometry of the metal center. Dimensionality is generally driven by the metal center which can have the ability to bond to as 16 functional sites on linkers. This number of possible bonds is the coordination number. Coordination numbers are more often between 2 and 10, and the bonding sites are separated by distinct angles. Coordination numbers are shown in planer geometry in Figure 2. In Figure 1 the 1D structure is 2-coordinated, the planer is 4-coordinated, and the 3D is 8-coordinated. Figure 3 shows structures hinting at the complexity that is possible by changing coordination geometry.

coordination site is also an option, albeit less probable — http://tinyurl.com/327p2nu — because хелатные полимеры is translated as chelate polymers much less frequently.

хелатные полимеры = КООРДИНАЦИОННЫЕ ПОЛИМЕРЫ, но в английском чаще говорят о последних.

КООРДИНАЦИОННЫЕ ПОЛИМЕРЫ (внутрикомплексные полимеры, хелатные полимеры, клешневидные полимеры), высокомол. соед., основная цепь к-рых построена из хелатных колец (см. Координационные соединения, Хелаты), Чаще всего координационные полимеры образуют катионы переходных металлов, хотя известны координационные полимеры металлов почти всех групп (кроме пятой) периодич. системы. Небольшие размеры катионов переходных металлов в сочетании с большим эффективным зарядом, а также наличие в ряде случаев незаполненных d-орбиталей обеспечивают довольно прочную связь металла с донорными группами лиганда. По строению осн. цепи различают координационные полимеры с основными неорг. цепями (ф-лы I) и элементоорг. цепями (II). — http://www.xumuk.ru/encyklopedia/2121.html

Because (1) they don't like borrowed words in the English language and (2) they like to name things by what actually defines them (in this case, coordination) rather than the attribute (in this case, multiple bonds to the same metal (which is called chelation).

Note to (1) — appearances to the contrary notwithstanding. :)

==========================================
coordination site news seems to be a better translation because the text, as it turned out, also contains 'координационная сфера' — http://tinyurl.com/39jdwxg — which cannot be translated by using linker
