Measurements of angular correlations between the <jats:italic>Z</jats:italic> boson and the closest jet are performed in events with at least one jet with <jats:italic>p</jats:italic><jats:sub>T</jats:sub> ≥ 500 GeV. Event topologies of particular interest are the collinear emission of a <jats:italic>Z</jats:italic> boson in dijet events and a boosted <jats:italic>Z</jats:italic> boson recoiling against a jet. Fiducial cross sections are compared with state-of-the-art theoretical predictions. The data are found to agree with next-to-next-to-leading-order predictions by NNLO<jats:sc>jet</jats:sc> and with the next-to-leading-order multi-leg generators M<jats:sc>ad</jats:sc>G<jats:sc>raph</jats:sc>5_<jats:sc>a</jats:sc>MC@NLO and S<jats:sc>herpa</jats:sc>.</jats:p>
