研究了单羟基冠醚配位体6-羟基-2,3,9,10-二苯并-1,4,8,11,14-五氧杂环十六-2,9-二烯(L)对钙和镧系元素的竞争配位反应,发现该配位体在我们的实验条件下对钙的配位能力要明显大于对重稀土的配位能力;同时研究了标题大环配位体和钙的配位化合物的晶体结构,该配位化合物的分子结构式为[Ca(NO_3)(H_2O)L](NO_3),M_r=528.47,晶体属单斜晶系,α=1.5285(6),b=0.9713(3),c=1.5134(7)nm,β=98.79(3)°,V=2.2205nm~3,D_(ex)=1.531g/cm~3,D_c=1.527g/cm~3,Z=4,空间群为P2_1/c.
Hydroxy-2,3,9,10-dibenzo-1,4,8,11,14-pentacyclohexadeca-2,9-diene (L ) On calcium and lanthanide competitive coordination reaction and found that the ligand in our experimental conditions, the coordination ability of calcium was significantly greater than the heavy rare earth coordination ability; the title macrocyclic ligand The crystal structure of the coordination compound is as follows: [Ca (NO_3) (H_2O) L] (NO_3), M_r = 528.47, the crystal is monoclinic, α = 1.5285 b = 0.9713 (3), c = 1.5134 (7) nm, β = 98.79 (3) °, V = 2.2205 nm -3, D ex = 1.531 g / cm 3, and D c = 1.527 g / cm 3 , Z = 4, space group P2_1 / c.
