Auto flex max lrf

The chemicals and solvents used to synthesize the ligand and CP were reagent grade and were used without further purification. Cd(OAc)₂·2H₂O, Pb(NO₃)₂, sodium thiocyanate (NaSCN), 3-methoxy-2-hydroxybenzaldehyde, and 2-hydroxy-1,3-diaminopropane were purchased from the Sigma Aldrich Company, USA. Elemental analysis (CHN) and mass spectrometry were carried out using a PerkinElmer 2400 CHN elemental analyzer and MALDI-TOF: Bruker Auto flex max LRF. IR and Raman spectra were recorded as KBr pellets (4000–400 cm⁻¹) using a PerkinElmer spectrum RX 1 and BRUKER RFS 27 (4000–50 cm⁻¹) model. ¹H and ¹³C NMR spectra were collected on a Bruker 400 MHz and 75.45 MHz FT-NMR spectrometer using TMS as an internal standard in DMSO-d₆. BRUKER AXS carried out PXRD measurements and a GERMANY X-ray diffractometer D8 FOCUS model with Cu Kα-1 radiation was used. UV-visible spectra of the ligand (CH₃OH) and the complex (DMF) (200–1100 nm) were determined using a Hitachi model U-3501 spectrophotometer.
