Mononuclear [Zn(FcCOO)(DTBbpy)2]ClO4.(H2O)3 (1) and dinuclear [Cd2(FcCOO)2(DTBbpy)4]ClO4·(H2O) (2), [Pb2(FcCOO)2(DTBbpy)2(H2O)2]·ClO4 (3) (FcCOO&nbsp;=&nbsp;ferrocenecarboxylate, DTBbpy&nbsp;=&nbsp;4,4′-di-tert-butyl-bipyridyl) metal complexes have been synthesized and characterized by single crystal X-ray diffraction. It reveals that the Zn(II), Cd(II) and Pb(II) metal complexes have different coordination geometries [Zn and Pb&nbsp;=&nbsp;distorted octahedral, Cd&nbsp;=&nbsp;distorted pentagonal bipyramidal]. The compound 3 shows the hemidirected mode of coordination in the geometrical system due to the inert pair effect of the lone pair of an electron on Pb(II) metal atom. The molecules are further forms 2D &amp; 3D framework structure via intermolecular hydrogen bonding. All the three compounds exhibit strong fluorescence emission bands in the liquid state at ambient temperature, of which the emission maxima show red-shifted and the solution-state electrochemistry of compounds 1–3 in CH3CN has been investigated.

A mixed Cd(II) complex {[Cd(FcCOO)2(dpyam)(H2O)][Cd(dpyam)2 (H2O)2]·(ClO4)2·CH3OH} (1) (where FcCOO&nbsp;=&nbsp;ferrocenecarboxylic acid and dpyam&nbsp;=&nbsp;2,2′-dipyridylamine), has been synthesized and characterized by FT-IR, 1H &amp; 13C NMR, UV–Vis spectroscopy and elemental analysis. The molecular structure of compound 1 has been determined by the single crystal X-ray diffraction technique, which consists of mixed two different cadmium(II) complexes and two uncoordinated perchlorate ions. The crystal packing shows that the compound 1 self-assembled by intermolecular hydrogen bonding via pyridyl N–H⋯O and coordinated water O⋯H–O–H⋯O, to afford the molecule 2D supramolecular network. Compound 1 exhibits high-energy intraligand (π–π∗) fluorescence emission. In electrochemical studies of compound 1 shows negative potential compared with ferrocenecarboxylic acid due to formation of coordination complex with Cd ions. The antibacterial study against the distinct bacterial strains show compound 1 has significant activity.

Reaction of [Mn(2,2′-bpy)2(OAc)](ClO4)(H 2O) with a series of aromatic carboxylic acids yields new Mn(II)carboxylates [Mn(2,2′-bpy)2(L)](ClO4)} 2 (1-3), [Mn(2,2′-bpy)2(L)2] (4-5) and [Mn(2,2′-bpy)2(L)(H2O)](ClO4) (6) (L = 2-aminobenzoate (2-aba) (1), 4-hydroxybenzoate (4-hba) (2), thiophene-2- carboxylate (2-tca) (3), 2-hydroxynapthoate (2-hnapa) (4), 3,5- diisopropylsalicylic acid (dipsa) (5), 2,4,6-triisopropylbenzoate (tipba) (6)). The new compounds have been characterized with the aid of elemental analysis, spectroscopy, and single-crystal X-ray diffraction studies. Compounds 1-3, which have been synthesized from less bulky carboxylic acids, are dimeric in the solid-state. Compounds 4-6, which are derived from more bulkier aromaric carboxylic acids, exist as monomeric complexes. In the case of 6, where very bulky 2,4,6-triisopropyl benzoic acid is used as the starting material, only one carboxylate ligand binds to the metal, resulting in a cationic complex. Interestingly in all the six complexes, the C-H hydrogen atoms of the 2,2′-bpy ligands are involved in extensive hydrogen bonding with the carboxylate oxygen atoms of the adjacent molecules and hence form non-covalent 1-D or 2-D aggregates in the solid state. © 2010 Elsevier B.V.
