The two-dimensional sheet structure of (I), showing N—H⋯H—B dihydrogen-bonding interactions. (In the electronic version of this paper, red dotted lines show the contacts for the extended structure.) [Symmmetry codes: (i) − x, + y, − z; (ii) − x, + y, − z; (iii) + x, − y, ; (iv) x, 1 + y, z; (v) − x, + y, − z; (vi) − x, + y, − z; (vii) + x, − y, − + z.] |
