Key indicatorsSingle-crystal X-ray study T = 293 K Mean (C-C) = 0.002 Å R factor = 0.041 wR factor = 0.114 Data-to-parameter ratio = 14.3For details of how these key indicators were automatically derived from the article, see A view of the molecular packing in (I), viewed down the c axis. Dashed lines indicate hydrogen bonds.

One-pot mechanosynthesis of aromatic amides and dipeptides from carboxylic acids and amines

“…S47-S51, ESIz). Although the crystal structure of 4 was known (CCDC code KASKUL), 20 we now report a second monoclinic b-polymorph whose simulated pattern matches the one for the milling product (Fig. 1a).…”

Odd−Even Effects: Diamondoid and Quartz Networks by Bis(pyridylcarboxamido)alkanes Containing Alkyl Chains with an Odd Number of -(CH2)- Groups as Spacers

“…The even−odd effects on melting points and densities have already been explored in the case of n -alkanes, and α,ω-substituted dithiols, diols, diamines, and diacids . The expected trend in mp values was clearly seen in the case of phenyl analogues of reverse amides . In contrast, the analogues of 1 and 2 do not exhibit such trends in mp values (Figure a).…”

20(29)-Lupene-3β,28β-diacetate

“…With this background, we thought it very important to determine the stereochemistry of this compound. The X-ray crystal structure analysis of (I) is part of our ongoing study of the molecular structures and relative stereochemistry of biologically active natural products (Awan et al, 2005;Choudhary et al, 2006;Anjum et al, 2005).…”
