Both 1 : 1 and 1 : 2 complexes are formed by zinc(II) halides and triarylphosphines unless electronic and/or steric factors intervene. Tri-p-chlorophosphine (a weaker base than PPh 3 ) forms only a 1 : 1 complex, whereas bulky tri-(ortho-substituted phenyl)phosphines do not react. The complexes ZnX

## Abstract The condensation of bis(__o__βformylphenyl) selenide with 1,2βdiaminoethane or 1,3βdiaminopropane yielded the new macrocyclic ligands 1 and 2 in very good yields. Crystals of 1 are monoclinic, space group __P__2~1~/__c__ with __a__ = 10.0648(10) Γ , __b__ = 37.390(4) Γ , __c__ = 8.0073(11
