%X Syntheses and room-temperature single-crystal X-ray structure determinations are recorded for 2:1 adducts of 2-aminomethylpyridine ('amp') with lead(II) nitrate and thiocyanate . [(amp)2Pb(NO3)2]2 is triclinic, P&#299;, a 11.616(4), b 11.145(6), c 7.341(3) &#506;, &#945; 83.87(4), &#946; 89.17(3), &#947; 64.12(3)&#176;, Z = 1 dimer ; R was 0.043 for No 3529 independent 'observed' (I > 3&#963;(I)) reflections. [(amp)2Pb(SCN)2]2 is also triclinic, P&#299; , a 12.121(9), b 9.301(14), c 8.615(8) &#506;, &#945; 70.11(10), &#946; 84.00(7), &#947; 79.38(10)&#176;, Z = 1 dimer (R 0.033 for No 3467). Both complexes are centrosymmetric dimers ; the coordination environment is made up in each case of a pair of N,N&#176;-bidentate bases, one terminally bound anion (O,O&#176;-chelating nitrate or S-bonded thiocyanate ) and bridging anions. In the case of the thiocyanates, these bridge end-on, so that the lead(II) environment is seven-coordinate PbN5S2; in the nitrate, the anion chelates through two of its oxygen atoms, bridging via the third, so that the lead(II) environment is nine-coordinate PbN4O5. A 'problem structure', [(amp)2Pb(ClO4)2], monoclinic, C2/c (?), a 14.528(3), b 8.203(3), c 15.495(6) &#506;, &#946; 91.14(3)&#176;, Z = 4 f.u ., R 0.044 for No 1775, is also recorded, the crystal seemingly a disordered aggregate of [(N, N&#8242;-amp)2Pb(OClO3)2] moieties.
