Synthesis and Properties of Triphenyltin Molybdates with Chainlike Anions of the Type 1 ∞ [(Ph 3 Sn)MoO 4 ] – . The Crystal Structures of ( n Pr 4 N)[(Ph 3 Sn)MoO 4 ]·CH 3 CN, ( n Bu 4 N)[(Ph 3 Sn)MoO 4 ], [Zn(en) 2 (Ph 3 Sn) 2 (MoO 4 ) 2 ]·2DMF·EtOH, and [Cu(en) 2 (Ph 3 Sn) 2 (MoO 4 ) 2 ]·2DMF·EtOH

The reaction of Ph 3 SnCl, (R 4 N) 2 [Mo 6 O 19 ] and (R 4 N)OH in a molar ratio of 6:1:10 leads to the formation of (R 4 N)[(Ph 3 Sn)MoO 4 ] (R = n Pr ( 1 ), n Bu ( 2 )). Compounds 1· CH 3 CN and 2 have been charactarized by IR spectroscopy and single crystal X‐ray diffraction. 1· CH 3 CN forms orthorhombic crystals, space group P 2 1 2 1 2 1 with a = 1339.9(2), b = 1508.9(2), c = 1733.2(3) pm. 2 crystallizes in the monoclinic space group P 2 1 with a = 1342.6(2), b = 2280.3(4), c = 1344.0(2) pm, β = 118.34(1). Both compounds 1 and 2 consist of isolated R 4 N + cations and polymeric $\rm^{1}_{\infty}$ [(Ph 3 Sn)MoO 4 ] – chains with an alternating arrangement of Ph 3 Sn + and MoO 4 2– groups. Treatment of (Ph 3 Sn) 2 MoO 4 with bis(ethylenediamine)copper(II) succinate yields [Cu(en) 2 (Ph 3 Sn) 2 (MoO 4 ) 2 ] ( 3 ). The zinc derivative [Zn(en) 2 (Ph 3 Sn) 2 (MoO 4 ) 2 ] ( 4 ) is obtained similarly by reaction of (Ph 3 Sn) 2 MoO 4 with bis(ethylenediamine)zinc(II) formiate. Compounds 3· 2DMF · EtOH and 4· 2DMF · EtOH crystallize in the monoclinic space group P 2 1 / n with a = 1998.0(2), b = 1313.3(1), c = 2181.6(2) pm, β = 90.97(1)° for 3 and a = 2015.4(1), b = 1316.7(1), c = 2157.0(1) pm, β = 90.40(1)° for 4 . Like in the cases of 1 and 2, polymeric $\rm^{1}_{\infty}$ [(Ph 3 Sn)MoO 4 ] – chains are observed. The [M(en) 2 ] 2+ units (M = Cu, Zn) act as linkers between the $\rm^{1}_{\infty}$ [(Ph 3 Sn)MoO 4 ] – chains to give 2D layer structures with (6, 3) net topology.
