| Abstract: Report here are the synthesis and X-ray crystal structures of triphenylarsine oxide monohydrate Ph3AsO H2O(1) and its coordination compounds with triphenyltin chloride, tri (p-chlorophenyl)tin chloride and triphenyllead chloride [Ph3SnCl(OAsPh3)](2), [(CIPh)3SnCI(OAsPh3)](3) and [Ph3PbCl(OAsPh3)] (4).Crystal data (1) monoclinic, P21/n, a = 9.4604(7), b = 16.6347(7), c = 11.1544(11 )Å, p= 113.233(6), V= 1613.0(2)Å, Z =4, Dcalcd = 1.401g·cm-3, R = 0.0576, Rw = 0.0683; (2) monoclinic, P21/n, a = 18.235 (4), b = 18.203 (4), c = 18.917 (4)Å, = 94.07(3), V = 6263 (2)Å, Z = 8, Dcalcd = 1.501g cm-3, R = 0.0510, Rw = 0.0648; (3) triclinic, P21, a = 12.9787(11), b = 13.873(2), c =20.183(3)Å, a =98.051 (10), =99.176 (9), γ = 91.212(8), V = 3548(7)Å3, Z = 4, Dcalcd = 1.518g cm-3, R = 0.074, Rw = 0.1248; (4) monoclinic, P21/ n, a = 18.336(2), b = 18.316(2), c = 18.810(2)Å, 94.250(10), V= 6299.8 (11)Å3, Z = 8, Dcalcd = 1.679g cm-3, R = 0.0808, Rw = 0.1829, respectively.The triphenylarsine oxide crystallizes with one molecule of water hydrogen-bond to the oxygen atoms of two triphenylarsine oxide molecules.This ligand forms isostructural coordination compounds with triorganotin and triorganolead chlorides.There are two molecules of [Ph3MCI(OAsPh3)] in an asymmetric unit.The geometry at the tin or lead atom is closed to a trigonal bipyramid with the 3 aryl rings occupying the equatorial position while the chlorine and oxygen atoms in the axial position.The coordination geometry of the arsenic atom is essentially tetrahedral. |
