In this study, new complexes are produced by bonding of transition metal dinuclear chlorides (CoCl2.6H2O, MnCl2.4H2O, and FeCl2.6H2O) with a polychelated ligand called 9-Phenyl-2,3,7-trihydroxy-6-fluorone, represented by (L), in a 1:2 (metal: ligand) ratio. Applying the appropriate chemical and physical methods, such as melting points, molar electrical conductivity, magnetic sensitivity, FT-IR, UV-Visible, and mass spectrometric studies, the produced complexes were characterized. All complexes are non-electrolytic, according to analyzes of molar electrical conductivity. All complexes have an octahedral structure, according to studies of magnetic sensitivity and Uv-Visible spectra. The mass spectrometry measurements showed the presence of the molar mass bands of the complex and the appearance of other bands resulting from the fragmentation of the complexes. For the metallic complexes spectra, FT-IR revealed a shift in the shape and intensity of the complexes bands at lower frequencies. The bonding of the metal to the oxygen atom can be observed by this shift in the bond stretch of the ligands. The size of the coordination between the ligand and the ions of the metallic elements is the cause. The measurement of the complexes' melting point is high, which suggests that the resultant complexes are quite stable.

On the 31st of December 2019, China reported several pneumonia-like infections in Wuhan's Huanan Seafood Wholesale Market. Ten days later, a novel coronavirus (2019-nCoV) was announced by the Chinese center for disease control (CCDC). At that time, the genome sequence was publicly made available. The genome sequence analysis of the newly identified virus was found similar to 75-80% of the SARS-CoV clade and more than 88% of bat corona viruses. On January 30th, the World Health Organization (WHO) declared a state of emergency due to the COVID-19 epidemic. In March 2020, the WHO raised a state of emergency and declared that COVID-19 has become a pandemic. Unfortunately, Iraq confirmed the first cases of COVID-19 in February 2020. On April 25th, 46,135 tests were conducted in Iraq with 1763 positive cases. Although Iraq is making great efforts to contain the COVID-19 pandemic stimulating all the available capabilities, such as having a full lockdown and teaching people about the sickness danger, the numbers of cases and deaths started to dramatically increase in June. Now, on the 2nd of July, the infection and death cases were around 54 K and 2.2 K, respectively. Herein, we outline the challenges that the Iraqi health sector is facing to control the spread of COVID-19 with procedures followed so far. This could assist in understanding the severity of the situation and end up with a realistic understanding of it.
