Abstract: Crystals of cadmium zinc diborate, Cd_1.17Zn_0.83B₂O₅, have been obtained by spontaneous nucleation in a platinum crucible at 1072 K. The crystal structure exhibits diborate groups, B₂O₅^4-, sharing O atoms with considerably distorted M1O₆ octahedra and M2O₄ tetrahedra. Both metal centers are disordered in the proportion Cd:Zn = 0.92:0.08 on the M1 site and Cd:Zn = 0.25:0.75 on the M2 site. A strong second-harmonic generation has been observed for the title compound when excited with an Nd:YAG laser ( = 1064 nm).
