翻译一段话，汉语翻译为英语，晶体方面，求高手翻译！自己也在翻译，翻译过了对比下！

| 晶体结构属于单斜晶系，C2/c空间群。它具有以M原子为中心的扭曲的八面体几何构型，配体A与M配位的原子C、 N、O分别采取顺式、反式、顺式构象，这与以前报道的类似配合物的构象一致。从图中还可以看出：M（III）与苯环上的碳原子形成碳-金属键，而不是与萘环上的碳原子形成碳-金属键，并且，由配位形成的五元环（M1，C1，C6，C7，N1）平面的平均偏差为0.0608 Å，此平面与苯环（C1，C2，C3，C4，C5，C6）形成的二面角为6.5°，与噁唑杂环（N1，O1，C7-17）所形成的二面角为9.2°。由表可知：M-C键的平均键长为1.997Å；M-N键的平均键长为2.079Å，M-O键的平均键长为 2.141Å，这是因为从O原子到C原子，其电负性逐渐减小，成键原子间的共价成分增加导致的。从配合物的空间堆积图可以看出：两个分子的萘环之间相互平行且部分重叠，两平面间的距离为3.450Å，存在明显的π-π相互作用。 |

Crystal structure belongs to the monoclinic system, C2 / c space group. It possesses the distorted octahedron geometry structure at the center of M atomic. The A and M ligands in coordination with C, N, O atoms were respectively taken cis-form, anti-form, cisoid conformation, which is consistent with the reported conformation of similar complexes. From the graph, we can see that the M (III) and the carbon atom of benzene ring formed a carbon-metallic bond, but not the carbon atom of naphthalene ring. And the average deviation of the five-membered ring (M1, C1 C6, C7,, N1) plane from the coordination is 0.0608 & Aring. The dihedral angle between the above plane and benzene ring (C1, C3, C4, C2, C5, C6)is 6.5 °, and the dihedral angle between the above plane and Oxazole heterocyclic ring (N1, O1, 7-17) is 9.2 °.It indicates from the table that the average bond length of M-C is 1.997Å, the average bond length of M-N is 2.079Å, and the average bond length of M-O is 2.141Å.This is resulting from the electronegativity decreasing gradually and the covalent component of the bond atoms increasing from the O to C atom. It can be perceived from the space accumulation figure of the complexes that the naphthalene ring between two molecules is parallel and overlap, the distance between the two planes is 3.450 & Aring, with the obvious π-π interaction. |

| The coordination polymer crystallizes in the monoclinic system with space group of C2/c. The metal center is six coordinated with a slightly distorted octahedral geometry.The coordination conformation of the C, N and O atoms of the ligands adopt the cis ,trans and cis respectively,which is consistent with the similar reported complexes. It can be illustrated from the figure that the carbon-metal bond is formed between M (III) and the C atom on the benzene ring rather than the C atom on the naphthalene ring. Moreover, the average deviation of the five-membered ring formed with(M1, C1 C6, C7,, N1) is 0.0608 & Aring and the dihedral angle is 6.5 °with the benzene ring (C1, C3, C4, C2, C5, C6) and 9.2 °with the oxazole heterocyclic(N1, O1, C7-17). It shows from the table that the average bond distance of M-C is 1.997& Aring, the average bond distance of M-N is 2.079& Aring, and the average bong distance of M-O is 2.141 & Aring.The increase of the bond distance from M-C to M-N and M-O is caused by the increase of the covalent component between the coordination atoms from C to N and O of which the electronegativity decreases gradually. From the space accumulate figure, it can be seen that the naphthalene rings of two molecules are parallel and overlap with the distance of 3.450Å,and the obvious π-π interactions exist. |
