The P atom in the title molecule, C12H26N3OP, has a distorted tetrahedral configuration: its bond angles lie in the range 101.1 (2)–119.1 (2)°. The P—N bonds to the two cyclopentylamido moieties are significantly different ...

The asymmetric C atom in the title compound, C21H17BrClNO, is in a slightly distorted tetrahedral environment and the NH unit adopts a gauche orientation with respect to the CO group. In the crystal, pairs of intermolecular ...

In the asymmetric unit of the title salt, (C5H12NO)6[PMo12O40]2.5C5H11NO, there are two independent α-Keggin-type [PMo12O40]3– polyoxidoanions, which show characteristic features with respect to bond lengths and angles. ...
