A compound of formula (I): ##STR1## n which M is a transition metal ion; A is a counter-ion if required; r, s and t are independently 0 to 3 such that r+s+t is in the range of 1 to 3; R.sup.a, R.sup.b, R.sup.c are each independently hydrogen or CH.sub.2 OR' where R' is hydrogen or an organic group; B and E are independently oxygen, CH.sub.2, NR.sup.d in which R.sup.d is alkyl, hydrogen, alkylcarbonyl, or arylcarbonyl or SO.sub.n where n is 0 or an integer 1 or 2, with the proviso that B and E are not simultaneously CH.sub.2 and that when B is oxygen, NR.sup.d or SO.sub.n, then r cannot be 0, and when E is oxygen, NR.sup.d or SO.sub.n, then t cannot be 0; R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 are independently hydrogen, alkyl or alkoxy.
化合物的化学式(I):##STR1## 其中 M 是过渡金属离子;A 是必要时的对离子;r、s 和 t 分别独立取值为 0 到 3,使得 r+s+t 落在 1 到 3 的范围内;R.sup.a、R.sup.b、R.sup.c 分别独立取值为氢或 CH.sub.2 OR',其中 R' 是氢或有机基团;B 和 E 分别独立取值为氧、CH.sub.2、NR.sup.d,其中 R.sup.d 是烷基、氢、烷基羰基或芳基羰基或 SO.sub.n,其中 n 为 0 或整数 1 或 2,但需注意 B 和 E 不同时为 CH.sub.2,且当 B 为氧、NR.sup.d 或 SO.sub.n 时,r 不能为 0,当 E 为氧、NR.sup.d 或 SO.sub.n 时,t 不能为 0;R.sub.1、R.sub.2、R.sub.3、R.sub.4、R.sub.5、R.sub.6、R.sub.7、R.sub.8、R.sub.9 和 R.sub.10 分别独立取值为氢、烷基或烷氧基。
