3-Bromo-N-(3,5-di-tert-butyl-phen-yl)propanamide.

The title compound, C17H26BrNO, exhibits a small twist between the amide residue and the benzene ring [C-N-C-C torsion angle = 29.4 (5)°]. In the crystal, the amido NH group is involved in N-H⋯O hydrogen bonding, which connects mol-ecules into chains parallel to the c axis.

cis-Dimethyl-bis(triphenyl-arsine)platinum(II).

In the title compound, [Pt(CH(3))(2)(C(18)H(15)As)(2)], the Pt(II) atom adopts a distorted cis-PtAs(2)C(2) square-planar coordination geometry. In the crystal, mol-ecules inter-act via aromatic π-π stacking inter-actions [centroid-centroid separation = 3.6741 (18) Å].
