“…Cesium(I) derivatives of lactose, d-arabinose and l-arabinose also showed hydrogen bonding at 3520 cm -1 confirmed by the X-ray structural determination [14]. At the low-frequency, novel bands in the region 530 cm -1 were assigned to the wagging vibrational band of coordinated water in complex-1, 2 and 3; complex-4 did not show bands correlated to this vibrational mode [12,13,15,16]. The Cu-O bond, formed by the loss of hydrochloric acid in complex-1 and 3, and the Cu-N bond of all these complexes showed vibrational stretching in the region of 510 cm -1 and 472 cm -1 respectively [12,13,15,17].…”

A copper(II) compound, [CuL][CuL(OH 2 )]·ClO 4 ·0.5CH 3 OH, where L = 1,2-diaminobenzene-N,N -bis(3-methoxysalicylidenei mine), has been synthesized and characterized by means of spectroscopic methods and single-crystal X-ray structure determination. The compound crystallizes in the orthorhombic space group Cmc2 1 with unit cell dimensions a = 17.981(3) Å, b = 17.776(3) Å, c = 14.047(3) Å, V = 4489.8(14) Å 3 , Z = 4, R 1 = 0.0511, and wR 2 = 0.1267. The asymmetric unit of the compound contains one mononuclear [CuL] unit, in which the Cu atom adopts a squareplanar geometry, one mononuclear [CuL(OH 2 )] unit, in which the Cu atom adopts a square-pyramidal geometry, one perchlorate anion, and one half methanol solvate. The compound was tested for its antibacterial activities to assess its inhibiting potential.

“…The first and second peaks in SBL-Cl and SBL-Br which are 242 nm and 275 nm were due to the electronic transition of π → π* of the aromatic rings or C=N bond. While, the third peak of SBL-Cl (332 nm) and SBL-Br (333nm) are due to the transition of n → π* of the imine group (-NH-N=C-) in the hydrazone ligand [7]. By using Beer-Lambert Law, the molar absorptivity for both ligands were calculated in …”

Two novel Schiff Base ligands are used in this work. These amphiphilic ligands were being chosen because of the suitability in forming Langmuir film by using Langmuir technique. Characterizations of these ligands were carried out through LB t the surface pressure-mean molecular area (П (ΔV-A) isotherms. The analysis made from extrapolating the П the estimated area and the radius of the ligand molecules The UV-Visible spectrometer was used to study the optical properties of the ligands. This study was made in order to recognize the fundamental properties of these ligands for future works on detecting ions applications. Two novel Schiff Base ligands are used in this work. These amphiphilic ligands were being chosen because of the suitability in forming Langmuir film by using Langmuir-Blodgett (LB)technique. Characterizations of these ligands were carried out through LB technique to obtain mean molecular area (П-A) and surface potential-mean molecular area . The analysis made from extrapolating the П-A graphs led to the result of the estimated area and the radius of the ligand molecules oriented on the air-water subphase.Visible spectrometer was used to study the optical properties of the ligands.
