title: Heteronuclear Ru(II)Ag(I) complexes having a pyrroloquinolinequinone derivative as a bridging ligand.
abstract: Herein, we report the synthesis of a novel heterohexanuclear complex (1) of a heteroaromatic cofactor, pyrroloquinolinequinone (PQQ). The crystal structure of 1 was determined to reveal that two PQQ-bridged Ru(II)Ag(I) units were linked by two [Ag(I)(OTf)2](-) units (OTf = CF3SO3(-)). A solvent-bound Ru(II)Ag(I) heterodinuclear complex (2) was formed from 1 in a coordinating solvent such as acetone to show an intense metal-to-ligand charge-transfer band at 709 nm.
