In this review, gas-phase chemistry of interstellar media and some planetary atmospheres is extended to include molecular complexes. Although the composition, density, and temperature of the environments discussed are very different, molecular complexes have recently been considered as potential contributors to chemistry. The complexes reviewed include strongly bound aggregates of molecules with ions, intermediate-strength hydrogen bonded complexes (primarily hydrates), and weakly bonded van der Waals molecules. In low-density, low-temperature environments characteristic of giant molecular clouds, molecular synthesis, known to involve gas-phase ion-molecule reactions and chemistry at the surface of dust and ice grains is extended here to involve molecular ionic clusters. At the high density and high temperatures found on planetary atmospheres, molecular complexes contribute to both atmospheric chemistry and climate. Using the observational, laboratory, and theoretical database, the role of molecular complexes in close and far away is discussed.
在本综述中，星际介质和一些行星大气的气相化学被扩展到包括分子复合物。尽管所讨论环境的组成、密度和温度差异很大，但分子复合物最近被认为是化学过程的潜在贡献者。所综述的复合物包括分子与离子的强结合聚集体、中等强度氢键复合物（主要是水合物）以及弱结合的范德华分子。在巨分子云的低密度、低温环境中，已知涉及气相离子 - 分子反应以及尘埃和冰粒表面化学的分子合成在此扩展到涉及分子离子簇。在行星大气的高密度和高温条件下，分子复合物对大气化学和气候都有贡献。利用观测、实验室和理论数据库，讨论了分子复合物在近距离和远距离的作用。
