Fig. 1From: Can Nucleobase Pairs Offer a Possibility of a Direct 3D Self-assembly?Stereo image of the most energetically favorable heteroassociate of m1Cyt · m1Thy. Its T-shaped and stabilized by means of two H-bonds and two van der Waals contacts (represented by dotted line; their corresponding bond lengths H…B/A…B are given in Å). Note that the 1-methyl group of m1Thy actively interacts with the m1CytBack to article page
