Perspective views of the two structures along the a axis are shown in figure 1

The anion possesses m2m symmetry in that all four molybdenum atoms are coplanar Co1 occupy the special positions with a site occupancy factor (SOF) of 0.5.

Table 1 summarizes the crystal parameters and details of the structure solution and refinement. Three crystallographically independent(distinct) molybdenum. Each adopts a bipodal, corner-sharing motif. Adopt distorted triangular bipyramidal geometry. The anion resides on an inversion centre

Propagation of this motif in the ab plane results in a bilayer of parallel ….. strands. The distance is 1.60A, consistent with a V=O multiple bond

Each MoO6 octahedron is connected to adjacent PO4 tetrahedra through corner-sharing. Each MoO6 octahedron is connected to four phosphate tetrahedral by sharing corners.

Each MoO6 octahedron shares an edge with an equivalent neighboring octahedron and a vertex with Mo3O6

The seven MoO6 octahedra aggregate in the compact edge-sharing arrangement in a plane, resulting a Anderson structure,on both sides of this fragment two tripod cyclo-triarsenate(III) are fixed. Each AsO3 pyramid is bound to an oxygen atom belonging to the central MoO6 octahedron, and the O atom is also shared by another two MoO6 octahedra. In addition, each AsO3 is also bound to other arsenic atoms thus closing the AS3O6 ring.

The three P atoms are linked to three adjacent indium atoms, with the fourth coordination site in each case corresponding to a terminal P-OH group as shown by the longer P-O distances.三個(gè)P原子與三個(gè)鄰近的銦原子配位，它們的第四個(gè)配位點(diǎn)都與端基P-OH（體現(xiàn)在P-O較長(zhǎng)）對(duì)應(yīng)。

All these O atoms are shared as common corners – three with P atoms and one with the three V atoms. The central molybdenum atom Mo(4) is in almost regular MoO6 octahedral environment. Each V atom is coordinated by six O atoms in a distorted octahedron.

The overall structure may be described as undulating layers constructed of Interlamellar region.

V/P/O layers constructed from (or built up from, or made up from)VO6 octahedra, VO5 square pyramids, and PO43- tetrahedral. The presence of triangular bipyramidal centers as opposed to octahedral centers causes distortions of the MOPO4 layer. V1 and V2 exhibit highly distorted octahedral geometries.

The {VO6} polyhedra are defined by three oxygen donors from each of three adjacent phosphates. Two short distances in the Mo1O6 are corresponded to two terminal oxygen atoms in cis position

Each of the Mo octahedral has two short molybdenum to oxygen bonds which define the molybdenyl groups Mo=O and commonly occur in Mo(VI) compounds.

Combining with/ decorated with Cu(II)-en groups

To explore more possibilities in open framework cobalt phosphate, hydrothermal reactions have been carried out in the system of CoO-P2O5-amine-H2O.herein, a new organically templated cobalt phosphate, is reported .which has a novel open framework structure built from four-,five-,and six-coordinated cobalt atoms and PO4 tetrahedra.

Built up by alternation of eight- and four-membered rings.

Several Mo-O clusters combining with amine-ligated transition-metal fragments have been reported. As-Mo-O clusters decorated with transition metal-amine groups have not been reported.

In contrast to the rich structural chemistry of molybdenum phosphates, the Mo-As-O system remains relatively undeveloped.

In each VO6, two of the O atoms are shared with the other two V atoms as common edges and two are shared with two PO4 as common corners. Of the remaining two O atoms, one is terminal with a short V=O bond of about 1.60A, the remaining O atoms

Cu(1) engages in corner-sharing interactions with a tetrahedral PO4 site.

There are three distinct CuII environments: one rest in the porphyrin pocket…while the remaining two O(2) bridges over two Mo atoms within a Mo2O10 unit.

The connectivity between the polyhedral units form [Fe (P8 Mo12 ) ]discrete building units that are connected by FeO6 octahedra giving rise to one-dimensional chain-like structure with eight-membered apertures.
