Item Description
The 2D Cartesian x coordinate of the position of this atom in a
recognisable chemical diagram. The coordinate origin is at the
lower left corner, the x axis is horizontal and the y axis
is vertical. The coordinates must lie in the range 0.0 to 1.0.
These coordinates can be obtained from projections of a suitable
uncluttered view of the molecular structure. If absent, values
will be assigned by the journal or database staff.
