N-bonded TCNQ in stacked dimeric systems. Synthesis and crystal structure of [Ru(PPh3)2(TCNQ)]2(TCNQ = 7,7,8,8-tetracyanoquinodimethane)
Abstract
The reaction of [Ru(CO)2(PPh3)2(thf)2](BF4)2(thf = tetrahydrofuran) with PPh3 in CH2Cl2 and LiTCNQ in methanol leads to the formation of [Ru(PPh3)2(TCNQ)]; the crystal structure of this compound shows a tetrahedral environment of the ruthenium atom with the TCNQ molecule coordinated via N.
