“…1) differ by 0.014A, but the bond distances are compatible with known values: a P---43 bond distance of 1.586 A in substituted dioxaphosphocine (Naidu, Krishnaiah & Sivakumar, 1992) and P--C8HIsO4P O bond distances of 1.554 and 1.557/~ in diphenylphosphate (Jones, Kirby & Parker, 1992). The P--C and the ~ bond distances are compatible with literature values for similar systems (Sawka-Dobrowolska & Rulko, 1987;Golen, 1993). As in similar systems, short C---C bond distances [1.336 (14) and 1.385 (18) ,~], along with high thermal motion, were noted for the ethyl C atoms (Hazel & Collin, 1972;Ezra & Collin, 1973).…”
