Syntheses, characterization, and reactivity of manganese and rhenium dioxime complexes. X-ray crystal structure of MnII(CDO)(CDOH)2(BPh(OCH3))2, an unusual pseudoclathrochelate complex, and ReIIICl(CDO)(CDOH)2BPh

A number of uncapped and monocapped rhenium (III) complexes and a biscapped manganese (II) tris(dioxime) complex have been synthesized and fully characterized. The uncapped rhenium (III) tris(dioxime) complexes, ReCl(dioximeH) 2 (dioximeH 2 ), are neutral seven-coordinate complexes with a chloride occupying the seventh site. They can be capped at one end with a boronic acid to give ReCl(dioxime)(dioximeH) 2 BR
