There is a growing multidisciplinary effort to understand the political causes and consequences of the US deportation system amid rapidly changing policies and significant data limitations. I contribute to this timely work by considering how interactions between an increasingly empowered executive branch and a politically polarized Congress shape deportation policymaking. I apply a policy feedback approach, a theoretical lens that analyzes policies and polities as co-constitutive, and construct a novel dataset to computationally analyze how Congressmembers publicly responded on Twitter to the Trump administration’s implementation and suspension of the family separation policy in 2018, during which migrant parents were prosecuted and detained separately from their children. Findings suggest that Republican and Democratic Congressmembers are unlikely to respond to executive assertions of power on deportation, even when policies are highly unpopular among the public. This raises concerns about shared governance on deportation policy and its implications for migration and democracy.

New complex compounds of platinum (II) with the biologically active ligand monoethanolamine (HL), featuring cis-, trans- [Pt(H2L)2Cl2], [Pt(H2L)2Br2] structures, as well as tetramine [Pt(H2L)4]Cl2 types, were synthesized under various conditions. Studies indicate that in all the synthesized complexes, monoethanolamine is coordinated monodentately to the nitrogen atom of the amino group, and deprotonation of the hydroxyl group of the ligand does not occur. It was determined that the composition and structure of the obtained complexes are strongly influenced by the nature of the initial platinum salts and the synthesis conditions. For instance, when cis-[Pt(NH3Cl)2] is used as the initial platinum (II) salt, its interaction with monoethanolamine under specific conditions results in the formation of a cis-complex with the composition [Pt(H2L)2Cl2]. In an alkaline medium, the reaction of PtCl2 with monoethanolamine in a 1:10 ratio produces tetramine-type complexes [Pt(H2L)4]Cl2. The structure of the resulting trans-complex [Pt(H2L)2Cl2] was confirmed through X-ray diffraction analysis. Biological testing revealed that complexes I-IV exhibit varying levels of antitumor activity.
