Type: article
Abstract: The reaction of lithium amide LiN(Si(Me)3)2 and ditopic heterocyclic ligand benzo[1,2-d:4,5-d′]bis(thiazole)-2,6(3H,7H)-dithione (H2L) in dimethoxyethane (DME) affords the binuclear molecular complex Li2L(DME)4 (I). New compounds [[Li2L(ДМСО)4 • (ДМСО)2]n (II) and [Li2L(ДМСО)4 • (ТГФ)2]n (III) are prepared by the recrystallization of compound I using a DMSO–diethyl ether or DMSO/THF mixture of solvents, respectively. According to the XRD data, these compounds are one-dimensional metalorganic frameworks (MOFs) differed by the arrangement of the bis(thiazole) fragments relative to each other and the Li2O2 fragment in the polymer chain, which affects the luminescence properties. The molecular structures of compounds I–III are determined by XRD (CIF files CCDC nos. 2334192 (I), 2334193 (II), and 2334194 (III)).
