Two new saccharinate/NH3 complexes of composition [Ni(sac)2(NH3)4] and [Zn(sac)2(NH3)2] were obtained and their crystal structures determined by single crystal X-ray diffractometry. The elongated octahedral Ni(II) complex crystallizes in the monoclinic P21/c space group with Z=2 whereas the tetrahedral Zn(II) complex is triclinic (space group P-1 and Z=2). For [Ni(sac)2(NH3)4] the magnetic moment and electron absorption spectrum were obtained and discussed. The infrared spectra of both complexes were also recorded and briefly commented.
