N2  - Lead(II) perchlorate crystallizes from aqueous ethanol with 2,4,6-tris(2-pyridyl)-1,3,5-triazine (trz) as a 1 : 2 trihydrate adduct, [(trz)2Pb(OH2)(O2ClO2)](ClO4)·2H2O, as has been confirmed by a low temperature (ca .153 K) single crystal X-ray structure determination. The lead(II) environment is derivative of that of the previously recorded hydrated (rather than the methanol solvated) nitrate complex, comprising a pair of tridentate trz ligands, and, in place of the pair of bidentate nitrates, a unidentate water and an unsymmetrically bidentate perchlorate ion. A redetermination of the structure of bis(2-aminomethylpyridine)lead(II) bis(perchlorate) has resulted in a non-disordered model, still based upon the [Pb(amp)2(OClO3)2] entity, where amp = 2-aminomethylpyridine, but with eight independent molecules, devoid of any crystallographic symmetry, comprising the asymmetric unit of the structure, which is described in a larger unit cell of lower symmetry.
