The adducts 2>*L i> and the ionic compounds 2 and 2 have been isolated by treating 2> with L in the appropriate stoicheiometry.The crystal structures of i)2>2>*en (1) and i)2>2>*py (2) have been determined: (1), monoclinic, space group P21/c, with a=13.402(8), b=16.470(9), c=12.294(7) Angstroem, β=99.0(1) deg, and Z=4; (2), monoclinic, space group P21/n with a=21.28(1), b=8.35(1), c=16.27(1) Angstroem, β=99.5(1) deg, and Z=4.Diffractometer data were collected for both crystals and both structures were refined to R 0.073.In (1) the zinc atom is four-co-ordinate forming two Zn-N bonds to the bidentate ethylenediamine molecule and two Zn-S bonds to the monodentate dithiophosphate ligands.In (2) the zinc atom is five-co-ordinate being bonded to pyridine , and to two bidentate dithiophosphate ligands.One ligand is bonded to the metal more symmetrically than the other .The 31P n.m.r. spectra of a number of these compounds have been examined.A correlation between the positions of the resonances and the mode of bonding of the - groups to the metal has been established.
