The bitopic ligand 1,2-bis(1,2,4-triazol-4-yl)ethane (tr(2)eth) provides an unprecedented short-distance N(1):N(2)-triazole bridging of Cu(I) and V(IV) ions in poly[bis[mu(4)-1,2-bis(1,2,4-triazol-4-yl)ethane]di-mu(2)-fluorido-tetrafluoridodi-mu(2)-oxido-dicopper(I)divanadium(IV)], Cu(2)V(2)F(6)O(2)(C(6)H(8)N(6))(2). The Cu(I) ions and tr(2)eth linkers afford a two-dimensional square-grid topology involving centrosymmetric (tr)Cu(mu-tr)(2)Cu(tr) [tr is triazole; Cu-N = 1.9525 (16)-2.0768 (18) A] binuclear net nodes, which are expanded in a third dimension by centrosymmetric V(2)O(2)F(6) pillars. The concerted mu-tr and mu-O bridging between the Cu(I) and V(IV) ions allows a multi-centre accommodation of the vanadium oxyfluoride moiety on a cationic Cu/tr(2)eth matrix [Cu-O = 2.1979 (15) A and V-N = 2.1929 (17) A]. The distorted octahedral coordination of [VONF(4)] is completed by two terminal and two bridging F(-) ions [V-F = 1.8874 (14)-1.8928 (13) and 2.0017 (13)-2.1192 (12) A, respectively]. The resulting three-dimensional framework has a primitive cubic net topology and adopts a threefold interpenetration.
双位配体1,2 - 双（1,2,4 - 三唑 - 4 - 基）乙烷（tr(2)eth）在聚[双[μ(4)-1,2 - 双（1,2,4 - 三唑 - 4 - 基）乙烷] - 二 - μ(2)-氟 - 四氟 - 二 - μ(2)-氧 - 二铜（I）二钒（IV）]，Cu(2)V(2)F(6)O(2)(C(6)H(8)N(6))(2)中实现了前所未有的短距离N(1):N(2)-三唑桥连铜（I）和钒（IV）离子。铜（I）离子和tr(2)eth连接体形成了一种二维方格拓扑结构，涉及中心对称的（tr）Cu(μ-tr)(2)Cu(tr) [tr为三唑；Cu-N = 1.9525 (16)-2.0768 (18) Å]双核网络节点，这些节点通过中心对称的V(2)O(2)F(6)柱在第三维中扩展。铜（I）和钒（IV）离子之间协同的μ-tr和μ-O桥连使得钒氧氟部分能够在阳离子Cu/tr(2)eth基质上进行多中心容纳 [Cu-O = 2.1979 (15) Å且V-N = 2.1929 (17) Å]。[VONF(4)]的扭曲八面体配位由两个端基氟离子和两个桥连氟离子完成 [V-F分别为1.8874 (14)-1.8928 (13) Å和2.0017 (13)-2.1192 (12) Å]。所得的三维框架具有原始立方网络拓扑结构并呈现三重互穿。
