In the indicated phenylene ring of the supplied WP6 conformer, what is the internal C3-C1-C4 bond angle at ring carbon C1? Report the angle in degrees to two decimal places.

Use the supplied complete 150-atom WP6 XYZ attachment (asset S0005). Coordinates are in angstrom. Atom rows are numbered from 1 after the two header lines; a physical file line number is atom row + 2. Use this one supplied conformer without relaxation. Labels C1, C3, etc. below mean element plus XYZ atom row, not unique original PDB atom names. The phenylene-ring cycle is C1-C4-C5-C2-C6-C3-C1. The local connectivity of interest is C3-C1-C4; all three are carbon atoms in rows 3, 1 and 4, with row 1 the vertex. This asks for a local ring angle, not proof of whole-ring planarity.
