Abstract
Under hydrothermal conditions, the simple reactions between metal salts, aromatic polycarboxylic acids (4,4′-diphthalic anhydride ketone, dphahk; 4,4′-sulfoyldiphthalic anhydride, sdpha; pyridine-2,3-dicarboxylic acid, pdca) and N2H4·H2O with or without the presence of phenanthroline·H2O (phen) yielded four di(mono)acylhydrazidate-coordinated Cd2+/Zn2+ compounds as [Cd(DPHKH)(phen)]·1.75H2O 1, [Zn3(DPHKH)2(HDPHKH)2(phen)2]·8H2O 2, [Cd(SDPTH)(phen)(H2O)]·H2O 3 and [Zn(PDH)2(H2O)2] 4 (DPHKH = 4,4′-diphthalhydrazidatoketone hydrazone; SDPTH = 4,4′-sulfoyldiphthalhydrazidate; PDH = pyridine-2,3-dicarboxylhydrazidate). The di(mono)acylhydrazide molecules in the title compounds originated from the hydrothermal in situ acylation reactions of aromatic polycarboxylic acids with N2H4·H2O. It is noteworthy that another kind of hydrothermal in situ reaction was also observed when preparing compounds 1 and 2, namely the nucleophilic addition reaction between the keto group (of dphahk) and N2H4. The photoluminescence analysis indicates that the compounds in the different states (in the solid state or in aqueous solution) may exhibit different emission behaviors.
