摘要：

In the title compounds, 2-methyl-2-(4-methylpyridine)-1,3,2-benzodioxaborole, C13H14BNO2, and 2- (4-methylpyridine)-2-phenyl-1,3,2-benzodioxaborole, C18H16BNO2, boron has a distorted tetrahedral coordination geometry, the two O-B-C angles being greater and all other angles at boron smaller than the ideal tetrahedral value. Both structures contain two crystallographically independent molecules, and all corresponding geometrical parameters in them are essentially the same, except for minor torsional variations. Bond lengths involving boron are similar to those of related adducts of phenylcatecholborane, and longer than those in the parent compound itself and related compounds with trigonal planar boron.
