1,10-phenanthroline monohydrate (>99%, BDH Chemical Ltd., Poole, England), guanine (99%, ACROS), FeCl3 (>97%), silver nitrate (>99%), sodium hydroxide (>97%), acetone (>98%), chloroform (>99%), sulfuric acid (>95%)] (Sigma Aldrich), methanol (Absolut) (Hi Media Laboratories Ltd., India), KBr (for IR spectroscopy Uvasol®), dichloromethane (>99.5%), Mueller Hinton agar, and barium chloride (BLULUX Laboratories Ltd., India), and nitric acid (T.V. Industrial Estate, India) were used.
Melting points were determined using STONE, STAFFORDSHIRE, ST15 OSA, UK, digital melting point apparatus. Molar conductivities of 10-4 M solutions of the solid complex in double distilled water were measured using Jenway 4200 conductivity meter. Elemental analyses were performed using a PERKIN ELMER 2400 CHN elemental analyzer. The electronic absorption spectra in the (200-800 nm) range were obtained in double distilled water on a Shimadzu UV-1700 UV-Visible spectrophotometer. FTIR spectra were recorded on a Perkin-Elmer frontier promotion cod ILC38B6PD7 spectrometer (4000-450 cm-1) in KBr pellets. HR-ESI spectra was conducted on dual ionization ESCi® (ESI/APCi) source options Waters LCT Premier XE (Waters Corp., Manchester, UK) at Academia Sinica, Institute of Chemistry, Taiwan. Iron content was determined by PerkinElmer, Optima 7300V HF Version ICP-OES spectrometer, digesting 1.6 mg of each complex in concentrated nitric acid and diluting them using double distilled water. The current-voltage measurements were performed using CHI 760d Electrochemical Workstation (Texas, USA) connected to a personal computer with a conventional three-electrode system. Carbon paste electrode (CPE) as a working electrode, platinum coil as a counter electrode, and Ag/AgCl (3M KCl) as a reference electrode were used. Cyclic voltammograms of 2.0 mM aqueous solution of the complexes at the carbon paste electrode (CPE) were recorded within the potential window of 0.2 to 1.1 V. Chloride ions were determined thermo-gravimetrically using the AgCl precipitate obtained from the mixture of 10 mL solution of 11 mg of each complex in distilled water with excess AgNO3 solution.
