摘要：

C22H26BNO2SI, M(r) = 375.4, orthorhombic, P2(1)2(1)2(1), a = 10.055 (3), b = 11.385 (3), c = 18.928 (4) angstrom, V = 2167 (3) angstrom 3, Z = 4, D(x) = 1.15 g cm-3, lambda-(Mo K-alpha) = 0.71073 angstrom, mu = 1.2 cm-1, F(000) = 800, T = 294 K, R = 0.0352 for 2217 observed refections. The tetrahedral -BO2NC and -SiO(Me)Ph2 units are joined through a B-O-Si bridge [B-O 1.439 (4), Si-O 1.585 (2) angstrom, B-O-Si 152.2 (2)-degrees]. The BOC3N ring has a chair conformation with B-O 1.461 (3) and B-N 1.639 (4) angstrom. The molecules are linked to form infinite chains extending in the a direction by hydrogen bonding between N-H units and the adjacent O(ring) atom of a molecule related by a 2(1) screw axis; the N...O distance is 2.971 (3) angstrom.
