The recent determination of the three-dimensional crystal structure of a dickite:formamide intercalate allows insight into the clay:organic bonding schemes of amides and other small organic molecule intercalates of the kaolin minerals. It is demonstrated that the observed basal spacings of intercalates with these molecules are consistent with hydrogen bonding schemes in which, if possible, triple hydrogen bonds from the clay hydroxyls to 0=C< are formed. Variations in basal spacing within a series of amides can be explained by considering the maximization of hydrogen bonding while avoiding close van der Waals contacts.

Резюме

Резюме

Недавнее определение трехразмерной кристаллической структуры включений диккита: формамида позволяет детальнее изучить глину: органические связывающие схемы амидов и других малых органических молекулярных включений каолиновых минералов. Показывается, что наблюдаемые основные промежутки между включениями и этими молекулами согласуются с водородными связывающими схемами, в которых, если возможно, из глинистых гидроксилов формируются тройные водородные связи 0=с<. Различия в основных промежутках в пределах серий амидов могут быть объяснены максимизацией водородных связей при отсутствии тесных контактов Ван дер Ваалса.

Kurzreferat

Die neue Bestimmung der dreidimensionalen Kristallstruktur einer Dickit-Formamideinbettung erlaubt Einblicke in die Bindungsweise der Einbettungen von organischen Amiden und anderen kleinen organischen Molekülen mit Kaolinmineralien. Es wurde gezeigt, daß die erhaltenen Basisabstände von Einbettungen mit diesen Molekülen im Einklang mit Wasserstoffbrückenschemen sind, in welchen, wenn möglich, dreifache Wasserstoffbrücken von den Tonhydroxylgruppen zu den Karbonylgruppen geformt werden. Variationen in den Basisabständen innerhalb einer Serie von Amiden können erklärt werden, indem die Maximisation von Wasserstoffbrücken und zur selben Zeit das Vermeiden von zu nahen van der Waalschen Kontakten berücksichtigt werden.
