3392(7), b = 5.2216(5), and c = 7.5264(6) A, alpha = 95.547(10), beta = 78.101(6), and gamma = 104.714(13) degrees, V = 309.51(5) A(3), and Z = 1. The final values were wR(p) = 0.0452, R(p) = 0.0340, and chi(2) = 1.99. The 1D polymeric motif built on axial Rh.O interactions of the centrosymmetric dirhodium units has been confirmed for the solid-state structure of 1. Compound 2,6-diselenaspiro[3.3]heptane
一种新的杂化产品的晶体结构,该产品由两个刚性构件组成,即四乙酸乙二酯(II),[Rh(2)(O(2)CCH(3))(4)](1)和2,6- diselenaspiro [3.3]庚烷,Se(2)C(5)H(8)(2),已使用实验室源X射线粉末衍射(XRPD)数据从头解决。刚体细化方法已应用于协助找到合适的模型并减少细化参数的数量。复数[Rh(2)(O(2)CCH(3))(4).mu(2)-Se(2)C(5)H(8)-Se,Se'](3)符合三斜晶格参数为a = 8.1357(4),b = 8.7736(4)和c = 15.2183(8)的单位晶胞A,alpha = 77.417(3),beta = 88.837(3)和gamma = 69.276(4)度,V = 989.66(8)A(3),Z =2。选择了中心对称的P空间组进行计算。减少后的wR(p),R(p)和chi(2)的最终值计算为0。分别为0579、0
