By the simple hydrothermal self-assembly, four new monoacylhydrazidate-coordinated compounds [Mn(APTH)(2)(H(2)O)] 1, [Pb(APTH)(2)]·0.25H(2)O 2, [Pb(2)(EPDH)(4)(H(2)O)] 3 and [Pb(MPDH)(2)] 4 (APTH = 3-aminophthalhydrazidate, EPDH = 5-ethylpyridine-2,3-dicarboxylhydrazidate, MPDH = 6-methylpyrinde-2,3-dicarboxylhydrazidate) were obtained. It is noteworthy that APTH was derived from the in situ
