Abstract
The preparation is described of some complexes of benzoxazole (L) with halides and nitrates of Co(II), Ni(II), Cu(II), and Zn(II)(M). With the exception of CuBr2L, all halide complexes were of the type ML2X2; with the exception of CuCl2L2, which was planar, the complexes had either tetrahedral or octahedral stereochemistry. The octahedral complexes all contained bridging halide atoms. Co(II) and Ni(II) nitrates formed the dihydrate, concontaining unidentate nitrate; heating to 140° dehydrated the complex, resulting in complexes containing bidentate nitrate groups.
