(a) A tape motif composed of a specific arrangement of water molecules (marked by letter W) and general atoms (marked by letter X). General atoms can match any element except C and H. Dotted lines indicate hydrogen bonds. This motif falls into the category T6(2). (b) The CSD entry AMIMZC10, showing the presence of the T6(2) motif. The dark-purple lines represent query connections. Two types of connections are specified: short connections with distance criteria less than the sum of the van der Waals radii and long connections greater than the sum of the van der Waals radii plus 0.35 Å. |
