SILVER(I) COORDINATION BY 1-(T-BUTYL)-2-BENZOYLAZIRIDINE

The reaction between AgNO3 and 1-(t-butyl)-2-benzoylaziridine (tBBA) l eads to the formation of bis-(1-(t-butyl)-2-benzoylaziridine) nitrato silver (1) which is a new metal aziridine derivative. The crystal stru cture was established by X-ray diffraction. [Ag(tBBA)2(NO3)] crystalli zes in space group C222(1) with a = 11.877(6), b = 13.560(4), c = 16.9 23(4) angstrom and Z = 4. The silver atom is six-coordinated by two N atoms of two azifidine rings (Ag-N = 2.39(1) angstrom), two 0 atoms of two benzoyl groups (Ag-0 = 2.60(l) angstrom) and two 0 atoms of the n itrato group (Ag-0 = 2.60(1) angstrom). The coordination around the si lver atom defines a very distorted octahedron with the C2 symmetry. Th e twofold axis passes through one 0 and the N nitrato atoms, and the s ilver atom. The nitrato group and tBBA act as bidentate ligands. These results are in contrast with our previous studies on azifidine zinc ( II) complexation where the zinc atom is not coordinated by the benzoyl group.
