The first experiment using radioactive beams post-accelerated by the HIE-ISOLDE facility has enabled to obtain a precise set of 𝐵⁡(𝐸⁢2) transition probabilities in neutron-rich  
74,76
 Zn 
  isotopes. The resulting 𝐵(𝐸⁢2; 2+
1→0+
1) values are consistent with those determined in earlier REX-ISOLDE measurements. While the 𝐵(𝐸⁢2; 4+
1→2+
1) transition probability in  
76
 Zn 
  is also in agreement with earlier Coulomb-excitation results, the value obtained for  
74
 Zn 
  is considerably lower. For the first time, a spectroscopic quadrupole moment of the 2+
1 state was measured for an exotic nucleus in this mass region. A detailed comparison is presented with large-scale shell-model and Monte Carlo shell-model calculations.
