A series of ruthenium(II) hydrido complexes containing crown thioethers, trans-RuH(Cl)(syn-L) (4, L Me4[l4]aneS4; 5, L Me6 [15]aneS4; 6, L Me8[l6]aneS4), were prepared in good yields by treating the corresponding dichlorides cis-RuCl2L (1, L Me4[4]aneS4; 2, L Me6[15]aneS4; 3, L Me8[16]aneS4) with NaBH4 in MeOH for 4 and in EtOH for 5 and 6. The structures of 4 and 5 were elucidated by an
