Figure 2 An extended packing diagram viewed down the c* direction, showing the "herringbone" edge-to-face packing arrangements. Only atoms involved in short contacts to neighbouring atoms are labelled [Sym. codes: (i) −x + , y + , −z + ; (ii) −x + , y − , −z + ; (iii) −x + , y − , −z + ; (iv) −x + , y + , −z + ]. The O1⋯H8—C8 H-bonds are not shown but are oriented along the ac diagonal (approximately perpendicular to the page). |
