The asymmetric unit of the title compound, Ru(C(13)H(9)N(3))(C(15)H(11)N(3))(H(2)O)(2)·1.5C(3)H(6)O, consists of two crystallographically independent Ru(II) complexes. Each complex is approximately octa-hedral with the Ru(II) atom bound by an N,N'-coordinated 2-(2-pyrid-yl)-1,8-naphthyridine (pynp) ligand, a meridional 2,2':6',2''-terpyridine (tpy) ligand and one aqua ligand. The tpy ligand is coordinated in a planar tridentate fashion with the central N atom closest to the Ru(II) atom. The aqua ligand is trans to the pyridine N atom of pynp. The long Ru-O distances [2.150 (5) and 2.138 (5) Å] are typical for aqua ligands in polypyridyl ruthenium complexes. In the crystal, both intra-molecular O-H⋯N and inter-molecular O-H⋯O hydrogen bonds are observed.
标题化合物Ru(C₁₃H₉N₃)(C₁₅H₁₁N₃)(H₂O)₂·1.5C₃H₆O的不对称单元由两个晶体学独立的Ru(II)配合物组成。每个配合物近似八面体构型，Ru(II)原子与一个通过N,N'-配位的2-(2-吡啶基)-1,8-萘啶(pynp)配体、一个经式2,2':6',2''-三联吡啶(tpy)配体以及一个水配体配位。tpy配体以平面三齿方式配位，其中心N原子最靠近Ru(II)原子。水配体与pynp的吡啶N原子呈反位。在多吡啶钌配合物中，较长的Ru - O键长[2.150 (5)和2.138 (5) Å]是水配体的典型特征。在晶体中，观察到分子内的O - H⋯N和分子间的O - H⋯O氢键。
