在氩气保护下，采用水冷铜坩埚电弧熔炼法合成了Ti_（1.6）Os_（2.4）B_2单晶和固溶体Ti_（1-x）Fe_xOs_2 RhB_2（0单晶X射线衍射和能谱分析表明，新的类银相为六方晶系Ti1.6Os1.4RuB2结构（空间群为（Nr. 189），Z = 3），并且分别含有三角平面B4-单元和钛或混合钛/铁原子的一维链。
Single crystals of Ti1.6Os2.4B2 and the solid solution Ti1–xFexOs2RhB2 (0 < x < 0.5) were synthesized by arc-melting the elements in a water-cooled copper crucible under an argon atmosphere. The new silver-like phases, structurally characterized by single-crystal X-ray and EDX analyses, crystallize in the hexagonal Ti1.6Os1.4RuB2 structure type (space group (Nr. 189), Z = 3) and contain trigonal-planar B4-units and one-dimensional chains of titanium or mixed titanium/iron atoms, respectively.
