title: Coordinative N-->B bond formation and hydrogen-bonded molecular ladders in 2,5-bis[(N-->B)-(2-aminoethoxy)phenylboryl]thiophene.
abstract: The molecular structure of the title compound, C(20)H(24)B(2)N(2)O(2)S, is characterized by a twofold rotation axis passing through the S atom and the midpoint of the C-C single bond in the thiophene ring. A coordinative N-->B bond is present in the boroxazolidine ring and a single N-H...O hydrogen bond [H...O 1.93 (3) A, N...O 2.829 (3) A and N-H...O 172 (2) degrees] links the molecules into a molecular ladder.
