The CgP(Se)X series (X = H, F, Cl, Br and I; CgP = 6-phospha-2,4,8-trioxa-1,3,5,7-tetramethyladamant-6-yl) is generated by the addition of elemental Se to the corresponding CgPX. The crystal structures of CgPX (X = H, F, Cl, Br and I) and CgP(Se)X (X = F, Cl, Br and I) are compared. The JP,Se values are correlated with the P–Se distance and the electronegativity of X. For both the CgP(Se)X and the CgPX
生成 CgP(Se)X 系列(X = H、F、Cl、Br 和 I;CgP = 6-phospha-2,4,8-trioxa-1,3,5,7-tetramethyladamant-6-yl)通过将元素硒添加到相应的 CgPX 中。比较了 CgPX(X = H、F、Cl、Br 和 I)和 CgP(Se)X(X = F、Cl、Br 和 I)的晶体结构。JP,Se 值与 P-Se 距离和 X 的电负性相关。对于 CgP(Se)X 和 CgPX 系列,P-C 键长与 P-X 键长和 C –P–C 键角。这些趋势可以用 P 原子上的 δ+ 电荷来解释,这是在气相中计算出来的。锥角测量表明 CgPCl、CgPBr 和 CgPI 具有基本相同的空间体积。
