Muster aus H‐Brücken: ihre Funktionalität und ihre graphentheoretische Analyse in Kristallen

Abstract: deren Freundschaft in ihre Tage als Mannschaftskameraden im Softball-Team des Yale University Chemistry Department Anfang der sechziger Jahre zuriickreicht.Muster von H-Brucken in organischen Kristallen pladiertL2 -' 1. Es gab betrachtliches Interesse an dieser MethodeC7]. und es erschien uns notwendig, unsere fruheren formalen Darstellungen der Regeln zur Bestimmung von Graphensatzen zu erweitern. Dariiber hinaus erkannten wir in dem MaDe, in dem wir selbst Erfahrungen sammelten, und als Ergebnis zahlreicher … Show more

“…The macrocyclic molecule contains two intramolecular hydrogen bonds [N(11)-H··· O(4) and N(23)-H···O(16)], which link two diametrically opposite amide N-H groups to the next amide O atom around the ring, after an intervening ester group. These interactions form loops with a graph set motif [22] of S (10) (1 )]. Each of the intermolecular interactions links the molecules into extended chains which run parallel to the crystallographic x axis and have a graph set motif of C(11).…”

“…Davis, Shimoni & Chang, 1995). By contrast, in the structure of 4,4'-sulfonyldiphenol the hydroxy groups act as donors only while the sulfonyl-O atoms are the acceptors (Glidewell & Ferguson, 1996b); again, each molecule is hydrogen bonded to four others, forming planar nets characterized by the graph set R4(32) with, in addition, pairs of such nets interwoven to form bilayers.…”

“…In the other chain, atom O1B at (x, y, z) acts as donor to O2B at (-1 -x, ½ + y, -~ -z) giving similar chains but with the O--H...O hydrogen bonds all in the direction [010]. In each of the chains, the hydrogen-bonding motif has graph set C(12) (Etter, 1990;Bernstein et al, 1995). This chain formation utilizes only a single hydroxy-H atom per bis-phenol molecule so that the bonds O2n--H2n (n = A, B) are still available as hydrogen-bond donors.…”
