What is The crystal and molecular structure of dichloro(thiourea)tin(II) about?

## Crystals of dichloro(thiourea)tin(II), from tin(II) chloride and thiourea, are monoclinic, space group P21/c, with a =5.951(2), b=13.937( 4 ), c =8.883(3) A, (3 = III .13(2)'. The structure was solved by Patterson and Fourier techniques, and refined by full-matrix, anisotropic least-squares methods to a final R-value of 0.0348 for 943 independent, nonzero reflections with I > 30(I). The basic unit of the structure is the SnCl.$!X(NHz)z] unit (,%-Cl = 2.492(4) and 2.609(4) A, Sn-S = 2.704(4) 4, valence angles at tin = 88.0(l), 90.6(l), 93.5(l) ). These formula units are tightly bound into chains via chlorine and sulphur bridging, which are, in turn, weakly bound by interchain chlorine bridges into sheets which are reinforced by N-H. \* \*Cl hydrogen bonds. Additional N-H\* \* -Cl hydrogen bonds connect adjacent sheets forming a three-dimensional network.
