✦ Synopsis

Crystals of the molybdenum(III) metaphosphate (\mathrm{Mo}\left(\mathrm{PO}{3}\right){3}) were grown by chemical vapor transport with iodine ( (1173 \mathrm{~K} \rightarrow 1073 \mathrm{~K})). The structure was determined by single crystal (\mathrm{X})-ray diffraction. (\mathrm{Mo}\left(\mathrm{PO}{3}\right){3}) crystallizes in the monoclinic space group (I a), with (a=) 10.819(1) (\AA, b=19.515(3) \AA, c=9.609(1) \AA, \beta=97.74(1)^{\circ}), and (Z=12 . \mathrm{Mo}\left(\mathrm{PO}{3}\right){3}), and has a structure consisting of infinite chains of corner-sharing (\mathrm{PO}{4}) tetrahedra running along [001], bridged by isolated (\mathrm{MoO}{6}) octahedra. The octahedra are regular, with an average Mo-O distance of (2.084 \AA). The structure can also be viewed as containing infinite (\mathrm{MoP}{3} \mathrm{O}{14}) chains along [102], which are linked so as to define small tunnels running in the same direction. 1994 Academic Press.
