“…The complexes show a broad band in the 3650-2750 cm )1 range, assigned to the presence of coordinated or lattice water molecules or hydrogen bonding (inter-or intra-molecular) in the complexes (2-22) [27,28]. However, the m(NH) group appears in the 3425-3224 cm )1 range [27,28]. The complexes show a band in the 1759-1670 cm )1 range ( …”

“…As a result, the separation between the two m s (CO) bands is much larger in monodentate complexes, then, the ion found for complexes (Table 2), which are assigned to a bridging or terminal nitrate group [33,35,36]. The band appears in the 1390-1296 cm )1 range except for the complexes (4), (10), (11) and (21) indicates the m(CO) group [25,27]. The complexes (7), (11), (12), (16) and (21) show bands in the 330-260 cm )1 range corresponding however, complexes (4), (10)- (16), (20) and (21) show that bands in the 440-351 cm )1 range to the bridging chloride atom are due to the terminal coordinate chloride atom [37].…”

Mn II , Fe III , Co II , Ni II , Cu II , Zn II , La III , Ru III , Hf IV , Zr IV and U VI complexes of 4-methylphenylamino acetoacetylacetone hydrazone have been synthesized and characterized by elementals analyses, i.r., u.v.-vis. spectra, magnetic moments, conductances, thermal analyses (d.t.a and t.g.a) and e.s.r measurements. The i.r. data show that, the ligand behaves as a neutral bidentate type (10), (13) and neutral tridentate type (4), (11), (12) and (21) monobasic bidentate type (7) or monobasic tridentate type (and (22) or dibasic tridentate type (5), (9) and (17) towards the metal ion. Molar conductances in DMF solution indicate that, the complexes are non-electrolytes. The e.s.r spectra of solid complexes (8) and (10) show axial type spectra with g k > g ? > 2:0023, a d (x 2 -y 2 ) ground state with significant covalent bond character. However, complex (12), shows an isotropic type, indicating a octahedral manganese(II) complex. Antibacterial and antifungal tests of the ligand and some of its metal complexes are also carried out and it has been observed that, the complexes are more potent bactericides and fungicides than the ligand.

“…Bands at 1589, 1513 and 1326 cm À1 correspond to (C¼C) Ar , (CH¼C) Al and (C-O), respectively [25,27]. The complexes show a broad band from lattice water at 3660-3150 cm À1 , except 6, 7, 11, 12, 20 and 21; coordinated water appears at 3450-2750 cm À1 except in 8, 15, 17 and 20 [27][28][29]. Two types of hydrogen bonds (intra-and intermolecular) are observed at 3630-3000 and 3235-2435 cm À1 in 2-23 [26][27][28], (table 2).…”

A series of Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), La(III), Ru(III), Hf(IV), Zr(IV) and U(VI) complexes of phenylamino acetoacetylacetone hydrazone have been synthesized and characterized by elemental analyses, IR, UV-Vis, magnetic moments, conductances, thermal analyses (DTA and TGA) and ESR measurements. The IR data show that the ligand is neutral bidentate, monobasic bidentate, monobasic tridentate or dibasic tridentate towards the metal ion. Molar conductances in DMF indicate that the complexes are non-electrolytes. The ESR spectra of solid [(L)(HL)Cu 2 (NO 3 )(H 2 O)] Á 1/2H 2 O (10) and [(H 2 L)Cu(Cl) 2 (H 2 O) 2 ] (11) show axial spectra with g k 4g ? 42.0023 indicating d ðx 2 Ày 2 Þ ground state with significant covalent bond character. However, [(HL) 2 Mn 2 (Cl) 2 (H 2 O) 4 Á H 2 O (13) shows an isotropic spectrum, indicating manganese(II) to be octahedral. Antibacterial and antifungal tests of the ligand and some of its metal complexes revealed that the complexes are more potent bactericides and fungicides than the ligand.
