“…In the two complexes, both Mn(II) ions are six-coordinated in a distorted octa­hedral environment, but one Mn ion has a cis-N(5)O coordination geometry defined by four N atoms of the two chelating 2,2′-bipyrimidine (bpym) ligands, one N atom of a coordinating acetonitrile mol­ecule and one O atom of a water ligand, whereas the other Mn ion has a cis-N(4)O(2) coordination geometry defined by four N atoms of the two bpym ligands and two O atoms of water ligands. …”

“…Six coordination arises from four O atoms derived from three different HTTTA(2−) ligands, and two N atoms of the chelating phen mol­ecule. The incompletely deprotonated triazine ligand adopts a μ(3)-η(1):η(1):η(2) coordination mode, resulting in the formation of chains along the c axis based on Cd(2)O(2) dimeric units. …”

“…NH1-CPHs generally showed greater antioxidative activity than Alcalase protein hydrolysates (P < 0.05) as indicated by the higher 1,1-diphenyl-1-picryhydrazyl (DPPH) radical scavenging activity and ferrous chelating activity. Both Alcalase and NH1 protein hydrolysates were able to retard lipid peroxidation and β-carotene-linoleic acid oxidation. …”
