Abstract A symmetry analysis and a simple dangling bond model are presented for
the V-Zn in ZnGeP2, identifying a possible Jahn--Teller distortion mechanism which could naturally explain the localization of the defect wavefunction on two of the nearest-neighbouring P atoms, as deduced for the electron nuclear double resonance experiments.
