The structures of [PdCl(TeCH2CH2NMe2)(PPr3n)] (2b) [PdCl(TeCH2CH2NMe2)(PMePh2)] (2e), [PtCl(TeCH2CH2NMe2)(PMePh2)] (2i), and the related [PtCl(SeCH2CH2NMe2)(PEt3)] (3) were determined crystallographically, revealing a typical pattern of trans-positioned neutral N and P donor atoms in an approximately square planar setting. The molecules 2b, 2e, and 2i were calculated by TD-DFT methodology to understand the origin of the weak (epsilon approximate to 200 M-1 cm(-1)) long-wavelength bands at about 600 nm for Pd/Te complexes such as 2b or 2e, at ca. 460 nm for Pt/Te systems such as 21, and at about 405 nm for Me analogues such as 3. These transitions are identified as charge transfer transitions.
