N2  - Iron(II) and nickel(II) bis(ligand) complexes of 6-(5-methyl-1,2,4-oxadiazol-3-yl)-2,2&#8242;-bipyridine (L) are described. The ligand field in the iron complex is close to that at the singlet ( 1 A1) &rlarr2; quintet ( 5 T2) crossover and magnetic and M&ouml;ssbauer spectral evidence indicates that a spin transition occurs in salts of the iron complex but is centred above room temperature. The structures of &#91;FeL2&#93; &#91;CF3SO3&#93;2.CH3CN and &#91;NiL2&#93; &#91;BF4&#93;2.CH3CN were determined and both are very similar to the structures of the corresponding terpyridine complexes. Spectroscopic data indicate that for the iron complex &pi;-interaction between the metal and the ligand is less than that in the terpyridine system. &#91;FeL2&#93; &#91;CF3SO3&#93;2.CH3CN is monoclinic, space group P 21/c; a 8 . 232(5), b 25 . 273(10), c 17 . 306(10) &#197;, &#946; 92 . 37(3)&#176;, Z 4; &#91;NiL2&#93; &#91;BF4&#93;2.CH3CN is monoclinic, space group P 21/c; a 8 . 136(2), b 17 . 558(2), c 23 . 783(7) &#197;, &#946; 109 . 32(1)&#176;, Z 4.
