1,2,4-Triazole complexes,part X. Complexes of transition metal(II) cyanates and thiocyanates with 1-phenyl-1,2,4-triazole

Summary Complex formation of transition metal(II) cyanates and thiocyanates (Z) with 1-phenyl-I,2,4-triazole (1-PhTr) is described. An assignment of the i.r. spectra of free and coordinated 1-phenyl-1,2,4-triazole is given. The products are mononuclear M(1-PhTr)₄Z₁ and polvnuclear M(1-PhTr)₂Z₂ compounds. The former occur ascis andtrans isomers; the latter include bridging (thio)cvanates. A tetrahedral coordination is found for zinc complexes.Part IX, D. W. Engelfriet, G. C.
