title: (N→B)-4-Methyl-3-pyrid-yl[N-methyl-imino-diacetate-O,O',N]borane.
abstract: The title compound, C(11)H(13)BN(2)O(4), has a rigid bicyclic structure due to an intra-molecular nitro-gen-boron dative bond. The B atom is in a distorted tetra-hedron environment with a B-N bond length of 1.640 (2) Å, which is in good comparison with the values in analogues compounds. In the crystal, the mol-ecules are linked by weak C-H⋯O and C-H⋯N inter-actions, forming a three-dimensional network.
