N2  - Syntheses and single-crystal X-ray structure determinations are reported for a number of adducts of bismuth(III) nitrate with the aromatic bidentate base systems 2,2&#8242;-bipyridine (bpy) or 1,10-phenanthroline (phen). With bpy, a mononuclear 1 : 2 adduct is formed, &#91;(bpy)2Bi(O2NO)3&#93;, isomorphous with its rare earth counterparts, orthorhombic, Pbcn, a 16&#183;7634(8), b 8&#183;9970(4), c 15&#183;0099(7) &#197;, Z = 4, conventional R on &#124;F&#124; 0&#183;029 for No 2502 independent &#8216;observed&#8217; reflections. The Bi centre is 10-coordinate with two bidentate N-base ligands and three bidentate nitrate ligands. With phen the 10-coordinate 1 : 2 adduct &#91;(phen)2Bi(O2NO)3&#93; was readily obtained, while the 1 : 1 adduct proved elusive and a hydroxide-bridged dimer &#91;(phen)(ONO2)2Bi(&#181;-OH)2Bi(O2NO)2(phen)&#93; with eight-coordinate Bi centres was the sole product from all crystallization attempts. &#91;(phen)2Bi(O2NO3)3&#93; is monoclinic, C2/c, a 11&#183;258(5), b 17&#183;847(4), c 13&#183;044(5) &#197;, &#946; 100&#183;78(4)&#176;, Z = 4, R 0&#183;063 for No 1958, again isomorphous with its rare earth counterparts; &#91;(phen)(ONO2)2Bi(&#181;-OH)2Bi(O2NO)2(phen)&#93; is triclinic, P-1, a 8&#183;3251(6), b 8&#183;6315(6), c 10&#183;7650(8) &#197;, &#945; 111&#183;120(1), &#946; 93&#183;486(1), &#947; 102&#183;364(1)&#176;, Z = 1, dimer, R 0&#183;024 for No 2965. In all syntheses, dimethyl sulfoxide (dmso) was used as the supporting solvent; the structure determination of the dmso adduct &#91;(dmso-O)3Bi(O2NO)3&#93; is also recorded where the Bi centre is nine-coordinate with three bidentate nitrate ligands and three O-bound dmso ligands: monoclinic P21/n, a 11&#183;4136(6), b 12&#183;6682(7), c 13&#183;4959(7) &#197;, &#946; 100&#183;209(1)&#176;, Z = 4, R 0&#183;026 for No 4214.
