您可以使用 Python 中的 pymatgen 库来将这个数据转化为 cif 文件。请按照以下步骤进行：

1. 安装 pymatgen 库，可以使用 pip install pymatgen 命令进行安装；
2. 将数据中的结构和晶胞信息提取出来，然后使用 pymatgen 中的 Structure 类创建一个结构对象；
3. 将结构对象保存为 cif 文件，可以使用 to(fmt='cif') 方法进行保存。

以下是示例代码：

from pymatgen.core.structure import Structure

data = [[{"@module": "pymatgen.core.structure", "@class": "Structure", "charge": null, "lattice": {"matrix": [[4.34157255, 0.0, 2.50660808], [1.44719085, 4.09327385, 2.50660808], [0.0, 0.0, 5.01321616]], "a": 5.013216160673185, "b": 5.013216156734002, "c": 5.01321616, "alpha": 59.999999978449296, "beta": 60.00000000444201, "gamma": 59.999999976968624, "volume": 89.09109455639522}, "sites": [{"species": [{"element": "Te", "occu": 1}], "abc": [0.5, 0.5, 0.5], "xyz": [2.8943817000000003, 2.046636925, 5.01321616], "label": "Te", "properties": {}}, {"species": [{"element": "Ba", "occu": 1}], "abc": [0.0, 0.0, 0.0], "xyz": [0.0, 0.0, 0.0], "label": "Ba", "properties": {}}], "@version": "2019.7.30"}, 98.58577122703691]]

# 提取结构和晶胞信息
structure_data = data[0][0]
lattice_matrix = structure_data['lattice']['matrix']
species = [site['species'][0]['element'] for site in structure_data['sites']]
coordinates = [site['xyz'] for site in structure_data['sites']]

# 创建结构对象
structure = Structure(lattice_matrix, species, coordinates)

# 保存 cif 文件
structure.to(filename='structure.cif', fmt='cif')

执行完上述代码后，将会在当前目录下生成一个名为 structure.cif 的 cif 文件。
