Popis:	The hydrolysis of methyltin tris(diphenyl phosphate) in ether-methyl cyanide solution yielded a new tetranuclear methyltin cluster, [Me 2 Sn 2 (OH)(O 2 P(OPh) 2 ) 3 (O 3 POPh)]I 2 (1). Related derivatives resulted from the condensation reaction of phosphonic acids with n-butylstannonic acid in an acetone solution at room temperature, The hydrolys of methyltin tris(diphenyl phosphate)in ether-methyl cyanide solution yielded a new tetranuclear methyltin cluster, [Me 2 Sn 2 (OH)(O 2 P(OPh) 2 ) 3 (O 3 POPh)] 2 (1).Related derivatives resulted from the condensation reaction of phosphonic acids with n-butylstannonic acid in an acetone solution at room temperature, [R' 2 Sn 2 O(O 2 P(OH)R) 4 ] 2 ; R'=n-Bu, R=t-Bu (2); R'=n-Bu, R=Et (3). X-ray analysis reveals related cage structures for 1 and 2
