Abstract We report the X-ray crystal structures of three new basic zinc carboxylate complexes, [Zn4O(O2CR)6] where RC(CH3)3 (pivalate) or C6H5 (benzoate) and [Zn5(OH)2(O2CCHCHCH3)8]x (crotonate). The basic pivalate is orthorhombic, Cmc21, with a=18.609(1), b=11.027(1), c=22.439(1)A, Z=4; R=0.042 for 1887 unique observed reflections. The basic benzoate is monoclinic, P21/m, with a=10.818(2), b=18.527(3)
摘要我们报告了三种新型碱性羧酸锌配合物[Zn4O(O2CR)6]的X射线晶体结构,其中RC(CH3)3(新戊酸酯)或C6H5(苯甲酸酯)和[Zn5(OH)2(O2CCHCHCH3) 8] x(巴豆酸)。基本的新戊酸酯是正交晶系的Cmc21,a = 18.609(1),b = 11.027(1),c = 22.439(1)A,Z = 4; 对于1887年观察到的独特反射,R = 0.042。碱性苯甲酸酯是单斜晶系的,P21 / m,a = 10.818(2),b = 18.527(3),c = 12.170(2)A,β= 110.32(1)°,Z = 2; 对于3633个独特的观察到的反射,R = 0.036。基本巴豆酸盐为单斜晶系,P21 / n,a = 8.723(1),b = 21.957(2),c = 11.302(1)A,β= 90.94(1)°,Z = 2; 对于3049次独特的观察到的反射,R
